- <h1 align="CENTER">Content Negotiation</h1>
-
- <p>Apache's supports content negotiation as described in
- the HTTP/1.1 specification. It can choose the best
- representation of a resource based on the browser-supplied
- preferences for media type, languages, character set and
- encoding. It also implements a couple of features to give
- more intelligent handling of requests from browsers that send
- incomplete negotiation information.</p>
-
- <p>Content negotiation is provided by the <a
- href="mod/mod_negotiation.html">mod_negotiation</a> module,
- which is compiled in by default.</p>
- <hr />
-
- <h2>About Content Negotiation</h2>
-
- <p>A resource may be available in several different
- representations. For example, it might be available in
- different languages or different media types, or a combination.
- One way of selecting the most appropriate choice is to give the
- user an index page, and let them select. However it is often
- possible for the server to choose automatically. This works
- because browsers can send as part of each request information
- about what representations they prefer. For example, a browser
- could indicate that it would like to see information in French,
- if possible, else English will do. Browsers indicate their
- preferences by headers in the request. To request only French
- representations, the browser would send</p>
-<pre>
- Accept-Language: fr
-</pre>
-
- <p>Note that this preference will only be applied when there is
- a choice of representations and they vary by language.</p>
-
- <p>As an example of a more complex request, this browser has
- been configured to accept French and English, but prefer
- French, and to accept various media types, preferring HTML over
- plain text or other text types, and preferring GIF or JPEG over
- other media types, but also allowing any other media type as a
- last resort:</p>
-<pre>
- Accept-Language: fr; q=1.0, en; q=0.5
- Accept: text/html; q=1.0, text/*; q=0.8, image/gif; q=0.6,
- image/jpeg; q=0.6, image/*; q=0.5, */*; q=0.1
-</pre>
- Apache supports 'server driven' content negotiation, as
- defined in the HTTP/1.1 specification. It fully supports the
- Accept, Accept-Language, Accept-Charset and Accept-Encoding
- request headers. Apache also supports 'transparent'
- content negotiation, which is an experimental negotiation
- protocol defined in RFC 2295 and RFC 2296. It does not offer
- support for 'feature negotiation' as defined in these RFCs.
-
- <p>A <strong>resource</strong> is a conceptual entity
- identified by a URI (RFC 2396). An HTTP server like Apache
- provides access to <strong>representations</strong> of the
- resource(s) within its namespace, with each representation in
- the form of a sequence of bytes with a defined media type,
- character set, encoding, etc. Each resource may be associated
- with zero, one, or more than one representation at any given
- time. If multiple representations are available, the resource
- is referred to as <strong>negotiable</strong> and each of its
- representations is termed a <strong>variant</strong>. The ways
- in which the variants for a negotiable resource vary are called
- the <strong>dimensions</strong> of negotiation.</p>
-
- <h2>Negotiation in Apache</h2>
-
- <p>In order to negotiate a resource, the server needs to be
- given information about each of the variants. This is done in
- one of two ways:</p>
-
- <ul>
- <li>Using a type map (<em>i.e.</em>, a <code>*.var</code>
- file) which names the files containing the variants
- explicitly, or</li>
-
- <li>Using a 'MultiViews' search, where the server does an
- implicit filename pattern match and chooses from among the
- results.</li>
- </ul>
-
- <h3>Using a type-map file</h3>
-
- <p>A type map is a document which is associated with the
- handler named <code>type-map</code> (or, for
- backwards-compatibility with older Apache configurations, the
- mime type <code>application/x-type-map</code>). Note that to
- use this feature, you must have a handler set in the
- configuration that defines a file suffix as
- <code>type-map</code>; this is best done with a</p>
-<pre>
- AddHandler type-map .var
-</pre>
- in the server configuration file.
-
- <p>Type map files should have the same name as the resource
- which they are describing, and have an entry for each available
- variant; these entries consist of contiguous HTTP-format header
- lines. Entries for different variants are separated by blank
- lines. Blank lines are illegal within an entry. It is
- conventional to begin a map file with an entry for the combined
- entity as a whole (although this is not required, and if
- present will be ignored). An example map file is shown below.
- This file would be named <code>foo.var</code>, as it describes
- a resource named <code>foo</code>.</p>
-<pre>
- URI: foo
-
- URI: foo.en.html
- Content-type: text/html
- Content-language: en
-
- URI: foo.fr.de.html
- Content-type: text/html;charset=iso-8859-2
- Content-language: fr, de
-</pre>
- Note also that a typemap file will take precedence over the
- filename's extension, even when Multiviews is on. If the
- variants have different source qualities, that may be indicated
- by the "qs" parameter to the media type, as in this picture
- (available as jpeg, gif, or ASCII-art):
-<pre>
- URI: foo
-
- URI: foo.jpeg
- Content-type: image/jpeg; qs=0.8
-
- URI: foo.gif
- Content-type: image/gif; qs=0.5
-
- URI: foo.txt
- Content-type: text/plain; qs=0.01
-</pre>
-
- <p>qs values can vary in the range 0.000 to 1.000. Note that
- any variant with a qs value of 0.000 will never be chosen.
- Variants with no 'qs' parameter value are given a qs factor of
- 1.0. The qs parameter indicates the relative 'quality' of this
- variant compared to the other available variants, independent
- of the client's capabilities. For example, a jpeg file is
- usually of higher source quality than an ascii file if it is
- attempting to represent a photograph. However, if the resource
- being represented is an original ascii art, then an ascii
- representation would have a higher source quality than a jpeg
- representation. A qs value is therefore specific to a given
- variant depending on the nature of the resource it
- represents.</p>
-
- <p>The full list of headers recognized is available in the <a
- href="mod/mod_negotiation.html#typemaps">mod_negotation</a>
- documentation.</p>
-
-
- <h3>Multiviews</h3>
-
- <p><code>MultiViews</code> is a per-directory option, meaning
- it can be set with an <code>Options</code> directive within a
- <code><Directory></code>, <code><Location></code>
- or <code><Files></code> section in
- <code>access.conf</code>, or (if <code>AllowOverride</code> is
- properly set) in <code>.htaccess</code> files. Note that
- <code>Options All</code> does not set <code>MultiViews</code>;
- you have to ask for it by name.</p>
-
- <p>The effect of <code>MultiViews</code> is as follows: if the
- server receives a request for <code>/some/dir/foo</code>, if
- <code>/some/dir</code> has <code>MultiViews</code> enabled, and
- <code>/some/dir/foo</code> does <em>not</em> exist, then the
- server reads the directory looking for files named foo.*, and
- effectively fakes up a type map which names all those files,
- assigning them the same media types and content-encodings it
- would have if the client had asked for one of them by name. It
- then chooses the best match to the client's requirements.</p>
-
- <p><code>MultiViews</code> may also apply to searches for the
- file named by the <code>DirectoryIndex</code> directive, if the
- server is trying to index a directory. If the configuration
- files specify</p>
-<pre>
- DirectoryIndex index
-</pre>
- then the server will arbitrate between <code>index.html</code>
- and <code>index.html3</code> if both are present. If neither
- are present, and <code>index.cgi</code> is there, the server
- will run it.
-
- <p>If one of the files found when reading the directory does not
- have an extension recognized by <code>mod_mime</code> to designate
- its Charset, Content-Type, Language, or Encoding, then the result
- depends on the setting of the <a
- href="mod/mod_mime.html#multiviewsmatch">MultiViewsMatch</a>
- directive. This directive determines whether handlers, filters,
- and other extension types can participate in MultiViews
- negotiation.</p>
-
- <h2>The Negotiation Methods</h2>
- After Apache has obtained a list of the variants for a given
- resource, either from a type-map file or from the filenames in
- the directory, it invokes one of two methods to decide on the
- 'best' variant to return, if any. It is not necessary to know
- any of the details of how negotiation actually takes place in
- order to use Apache's content negotiation features. However the
- rest of this document explains the methods used for those
- interested.
-
- <p>There are two negotiation methods:</p>
-
- <ol>
- <li><strong>Server driven negotiation with the Apache
- algorithm</strong> is used in the normal case. The Apache
- algorithm is explained in more detail below. When this
- algorithm is used, Apache can sometimes 'fiddle' the quality
- factor of a particular dimension to achieve a better result.
- The ways Apache can fiddle quality factors is explained in
- more detail below.</li>
-
- <li><strong>Transparent content negotiation</strong> is used
- when the browser specifically requests this through the
- mechanism defined in RFC 2295. This negotiation method gives
- the browser full control over deciding on the 'best' variant,
- the result is therefore dependent on the specific algorithms
- used by the browser. As part of the transparent negotiation
- process, the browser can ask Apache to run the 'remote
- variant selection algorithm' defined in RFC 2296.</li>
- </ol>
-

-
- <td>Browser indicates preference with the Accept-Charset
- header field. Each item can have a quality factor. Variants
- can indicate a charset as a parameter of the media
- type.</td>
- </tr>
- </table>
-
- <h3>Apache Negotiation Algorithm</h3>
-
- <p>Apache can use the following algorithm to select the 'best'
- variant (if any) to return to the browser. This algorithm is
- not further configurable. It operates as follows:</p>
-
- <ol>
- <li>First, for each dimension of the negotiation, check the
- appropriate <em>Accept*</em> header field and assign a
- quality to each variant. If the <em>Accept*</em> header for
- any dimension implies that this variant is not acceptable,
- eliminate it. If no variants remain, go to step 4.</li>
-
- <li>
- Select the 'best' variant by a process of elimination. Each
- of the following tests is applied in order. Any variants
- not selected at each test are eliminated. After each test,
- if only one variant remains, select it as the best match
- and proceed to step 3. If more than one variant remains,
- move on to the next test.
-
- <ol>
- <li>Multiply the quality factor from the Accept header
- with the quality-of-source factor for this variant's
- media type, and select the variants with the highest
- value.</li>
-
- <li>Select the variants with the highest language quality
- factor.</li>
-
- <li>Select the variants with the best language match,
- using either the order of languages in the
- Accept-Language header (if present), or else the order of
- languages in the <code>LanguagePriority</code> directive
- (if present).</li>
-
- <li>Select the variants with the highest 'level' media
- parameter (used to give the version of text/html media
- types).</li>
-
- <li>Select variants with the best charset media
- parameters, as given on the Accept-Charset header line.
- Charset ISO-8859-1 is acceptable unless explicitly
- excluded. Variants with a <code>text/*</code> media type
- but not explicitly associated with a particular charset
- are assumed to be in ISO-8859-1.</li>
-
- <li>Select those variants which have associated charset
- media parameters that are <em>not</em> ISO-8859-1. If
- there are no such variants, select all variants
- instead.</li>
-
- <li>Select the variants with the best encoding. If there
- are variants with an encoding that is acceptable to the
- user-agent, select only these variants. Otherwise if
- there is a mix of encoded and non-encoded variants,
- select only the unencoded variants. If either all
- variants are encoded or all variants are not encoded,
- select all variants.</li>
-
- <li>Select the variants with the smallest content
- length.</li>
-
- <li>Select the first variant of those remaining. This
- will be either the first listed in the type-map file, or
- when variants are read from the directory, the one whose
- file name comes first when sorted using ASCII code
- order.</li>
- </ol>
- </li>
-
- <li>The algorithm has now selected one 'best' variant, so
- return it as the response. The HTTP response header Vary is
- set to indicate the dimensions of negotiation (browsers and
- caches can use this information when caching the resource).
- End.</li>
-
- <li>To get here means no variant was selected (because none
- are acceptable to the browser). Return a 406 status (meaning
- "No acceptable representation") with a response body
- consisting of an HTML document listing the available
- variants. Also set the HTTP Vary header to indicate the
- dimensions of variance.</li>
- </ol>
-
- <h2><a id="better" name="better">Fiddling with Quality
- Values</a></h2>
-
- <p>Apache sometimes changes the quality values from what would
- be expected by a strict interpretation of the Apache
- negotiation algorithm above. This is to get a better result
- from the algorithm for browsers which do not send full or
- accurate information. Some of the most popular browsers send
- Accept header information which would otherwise result in the
- selection of the wrong variant in many cases. If a browser
- sends full and correct information these fiddles will not be
- applied.</p>
-
- <h3>Media Types and Wildcards</h3>
-
- <p>The Accept: request header indicates preferences for media
- types. It can also include 'wildcard' media types, such as
- "image/*" or "*/*" where the * matches any string. So a request
- including:</p>
-<pre>
- Accept: image/*, */*
-</pre>
- would indicate that any type starting "image/" is acceptable,
- as is any other type (so the first "image/*" is redundant).
- Some browsers routinely send wildcards in addition to explicit
- types they can handle. For example:
-<pre>
- Accept: text/html, text/plain, image/gif, image/jpeg, */*
-</pre>
- The intention of this is to indicate that the explicitly listed
- types are preferred, but if a different representation is
- available, that is ok too. However under the basic algorithm,
- as given above, the */* wildcard has exactly equal preference
- to all the other types, so they are not being preferred. The
- browser should really have sent a request with a lower quality
- (preference) value for *.*, such as:
-<pre>
- Accept: text/html, text/plain, image/gif, image/jpeg, */*; q=0.01
-</pre>
- The explicit types have no quality factor, so they default to a
- preference of 1.0 (the highest). The wildcard */* is given a
- low preference of 0.01, so other types will only be returned if
- no variant matches an explicitly listed type.
-
- <p>If the Accept: header contains <em>no</em> q factors at all,
- Apache sets the q value of "*/*", if present, to 0.01 to
- emulate the desired behavior. It also sets the q value of
- wildcards of the format "type/*" to 0.02 (so these are
- preferred over matches against "*/*". If any media type on the
- Accept: header contains a q factor, these special values are
- <em>not</em> applied, so requests from browsers which send the
- correct information to start with work as expected.</p>
-
- <h3>Language Negotiation Exceptions</h3>
-
- <p>New in Apache 2.0, some exceptions have been added to the
- negotiation algorithm to allow graceful fallback when language
- negotiation fails to find a match.</p>
-
- <p>When a client requests a page on your server, but the server
- cannot find a single page that matches the Accept-language sent by
- the browser, the server will return either a "No Acceptable
- Variant" or "Multiple Choices" response to the client. To avoid
- these error messages, it is possible to configure Apache to ignore
- the Accept-language in these cases and provide a document that
- does not explictly match the client's request. The <a
- href="mod/mod_negotiation.html#forcelanguagepriority">ForceLanguagePriority</a>
- directive can be used to override one or both of these error
- messages and subsitute the servers judgement in the form of the <a
- href="mod/mod_negotiation.html#languagepriority">LanguagePriority</a>
- directive.</p>
-
- <p>The server will also attempt to match language-subsets when no
- other match can be found. For example, if a client requests
- documents with the language <code>en-GB</code> for British
- English, the server is not normally allowed by the HTTP/1.1
- standard to match that against a document that is marked as simply
- <code>en</code>. (Note that it is almost surely a configuration
- error to include <code>en-GB</code> and not <code>en</code> in the
- Accept-Language header, since it is very unlikely that a reader
- understands British English, but doesn't understand English in
- general. Unfortunately, many current clients have default
- configurations that resemble this.) However, if no other language
- match is possible and the server is about to return a "No
- Acceptable Variants" error or fallback to the
- <code>LanguagePriority</code>, the server will ignore the subset
- specification and match <code>en-GB</code> against <code>en</code>
- documents. Implicitly, Apache will add the parent language to
- the client's acceptable language list with a very low quality
- value. But note that if the client requests "en-GB; qs=0.9, fr;
- qs=0.8", and the server has documents designated "en" and "fr",
- then the "fr" document will be returned. This is necessary to
- maintain compliance with the HTTP/1.1 specification and to work
- effectively with properly configured clients.</p>
-
-
- <h2>Extensions to Transparent Content Negotiation</h2>
- Apache extends the transparent content negotiation protocol
- (RFC 2295) as follows. A new <code>{encoding ..}</code> element
- is used in variant lists to label variants which are available
- with a specific content-encoding only. The implementation of
- the RVSA/1.0 algorithm (RFC 2296) is extended to recognize
- encoded variants in the list, and to use them as candidate
- variants whenever their encodings are acceptable according to
- the Accept-Encoding request header. The RVSA/1.0 implementation
- does not round computed quality factors to 5 decimal places
- before choosing the best variant.
-
- <h2>Note on hyperlinks and naming conventions</h2>
-
- <p>If you are using language negotiation you can choose between
- different naming conventions, because files can have more than
- one extension, and the order of the extensions is normally
- irrelevant (see the <a
- href="mod/mod_mime.html#multipleext">mod_mime</a> documentation
- for details).</p>
-
- <p>A typical file has a MIME-type extension (<em>e.g.</em>,
- <samp>html</samp>), maybe an encoding extension (<em>e.g.</em>,
- <samp>gz</samp>), and of course a language extension
- (<em>e.g.</em>, <samp>en</samp>) when we have different
- language variants of this file.</p>
-
- <p>Examples:</p>
-
- <ul>
- <li>foo.en.html</li>
-
- <li>foo.html.en</li>
-
- <li>foo.en.html.gz</li>
- </ul>
-
- <p>Here some more examples of filenames together with valid and
- invalid hyperlinks:</p>
-
- <table border="1" cellpadding="8" cellspacing="0">
- <tr>
- <th>Filename</th>
-
- <th>Valid hyperlink</th>
-
- <th>Invalid hyperlink</th>
- </tr>
-
- <tr>
- <td><em>foo.html.en</em></td>
-
- <td>foo<br />
- foo.html</td>
-
- <td>-</td>
- </tr>
-
- <tr>
- <td><em>foo.en.html</em></td>
-
- <td>foo</td>
-
- <td>foo.html</td>
- </tr>
-
- <tr>
- <td><em>foo.html.en.gz</em></td>
-
- <td>foo<br />
- foo.html</td>
-
- <td>foo.gz<br />
- foo.html.gz</td>
- </tr>
-
- <tr>
- <td><em>foo.en.html.gz</em></td>
-
- <td>foo</td>
-
- <td>foo.html<br />
- foo.html.gz<br />
- foo.gz</td>
- </tr>
-
- <tr>
- <td><em>foo.gz.html.en</em></td>
-
- <td>foo<br />
- foo.gz<br />
- foo.gz.html</td>
-
- <td>foo.html</td>
- </tr>
-
- <tr>
- <td><em>foo.html.gz.en</em></td>
-
- <td>foo<br />
- foo.html<br />
- foo.html.gz</td>
-
- <td>foo.gz</td>
- </tr>
- </table>
-
- <p>Looking at the table above you will notice that it is always
- possible to use the name without any extensions in an hyperlink
- (<em>e.g.</em>, <samp>foo</samp>). The advantage is that you
- can hide the actual type of a document rsp. file and can change
- it later, <em>e.g.</em>, from <samp>html</samp> to
- <samp>shtml</samp> or <samp>cgi</samp> without changing any
- hyperlink references.</p>
-
- <p>If you want to continue to use a MIME-type in your
- hyperlinks (<em>e.g.</em> <samp>foo.html</samp>) the language
- extension (including an encoding extension if there is one)
- must be on the right hand side of the MIME-type extension
- (<em>e.g.</em>, <samp>foo.html.en</samp>).</p>
-
- <h2>Note on Caching</h2>
-
- <p>When a cache stores a representation, it associates it with
- the request URL. The next time that URL is requested, the cache
- can use the stored representation. But, if the resource is
- negotiable at the server, this might result in only the first
- requested variant being cached and subsequent cache hits might
- return the wrong response. To prevent this, Apache normally
- marks all responses that are returned after content negotiation
- as non-cacheable by HTTP/1.0 clients. Apache also supports the
- HTTP/1.1 protocol features to allow caching of negotiated
- responses.</p>
-
- <p>For requests which come from a HTTP/1.0 compliant client
- (either a browser or a cache), the directive
- <tt>CacheNegotiatedDocs</tt> can be used to allow caching of
- responses which were subject to negotiation. This directive can
- be given in the server config or virtual host, and takes no
- arguments. It has no effect on requests from HTTP/1.1 clients.
-

- J. Flavell's <a
