41 <p>This module is used to assign content metadata to the content
42 selected for an HTTP response by mapping patterns in the
43 URI or filenames to the metadata values. For example, the filename
44 extensions of content files often define the content's Internet
45 media type, language, character set, and content-encoding. This
46 information is sent in HTTP messages containing that content and
47 used in content negotiation when selecting alternatives, such that
48 the user's preferences are respected when choosing one of several
49 possible contents to serve. See
50 <code class="module"><a href="../mod/mod_negotiation.html">mod_negotiation</a></code> for more information
51 about <a href="../content-negotiation.html">content negotiation</a>.</p>
53 <p>The directives <code class="directive"><a href="#addcharset">AddCharset</a></code>, <code class="directive"><a href="#addencoding">AddEncoding</a></code>, <code class="directive"><a href="#addlanguage">AddLanguage</a></code> and <code class="directive"><a href="#addtype">AddType</a></code> are all used to map file
54 extensions onto the metadata for that file. Respectively
55 they set the character set, content-encoding, content-language,
56 and <a class="glossarylink" href="../glossary.html#media-type" title="see glossary">media-type</a> (content-type) of documents. The directive <code class="directive"><a href="#typesconfig">TypesConfig</a></code> is used to specify a
57 file which also maps extensions onto media types. </p>
59 <p>In addition, <code class="module"><a href="../mod/mod_mime.html">mod_mime</a></code> may define the <a href="../handler.html">handler</a> and <a href="../filter.html">filters</a> that originate and process
60 content. The directives <code class="directive"><a href="#addhandler">AddHandler</a></code>, <code class="directive"><a href="#addoutputfilter">AddOutputFilter</a></code>, and <code class="directive"><a href="#addinputfilter">AddInputFilter</a></code> control the modules
61 or scripts that serve the document. The <code class="directive"><a href="#multiviewsmatch">MultiviewsMatch</a></code> directive allows
62 <code class="module"><a href="../mod/mod_negotiation.html">mod_negotiation</a></code> to consider these file extensions
63 to be included when testing Multiviews matches.</p>
65 <p>While <code class="module"><a href="../mod/mod_mime.html">mod_mime</a></code> associates metadata
66 with filename extensions, the <code class="module"><a href="../mod/core.html">core</a></code> server
67 provides directives that are used to associate all the files in a
68 given container (<em>e.g.</em>, <code class="directive"><a href="../mod/core.html#location"><Location></a></code>, <code class="directive"><a href="../mod/core.html#directory"><Directory></a></code>, or <code class="directive"><a href="../mod/core.html#files"><Files></a></code>) with particular
69 metadata. These directives include <code class="directive"><a href="../mod/core.html#forcetype">ForceType</a></code>, <code class="directive"><a href="../mod/core.html#sethandler">SetHandler</a></code>, <code class="directive"><a href="../mod/core.html#setinputfilter">SetInputFilter</a></code>, and <code class="directive"><a href="../mod/core.html#setoutputfilter">SetOutputFilter</a></code>. The core directives
70 override any filename extension mappings defined in
71 <code class="module"><a href="../mod/mod_mime.html">mod_mime</a></code>.</p>
73 <p>Note that changing the metadata for a file does not
74 change the value of the <code>Last-Modified</code> header.
75 Thus, previously cached copies may still be used by a client or
76 proxy, with the previous headers. If you change the
77 metadata (language, content type, character set or
78 encoding) you may need to 'touch' affected files (updating
79 their last modified date) to ensure that all visitors are
80 receive the corrected content headers.</p>

119 <h2><a name="multipleext" id="multipleext">Files with Multiple Extensions</a></h2>
120 <p>Files can have more than one extension; the order of the
121 extensions is <em>normally</em> irrelevant. For example, if the
122 file <code>welcome.html.fr</code> maps onto content type
123 <code>text/html</code> and language French then the file
124 <code>welcome.fr.html</code> will map onto exactly the same
125 information. If more than one extension is given that maps onto
126 the same type of metadata, then the one to the right will
127 be used, except for languages and content encodings. For example,
128 if <code>.gif</code> maps to the <a class="glossarylink" href="../glossary.html#media-type" title="see glossary">media-type</a>
129 <code>image/gif</code> and <code>.html</code> maps to the
130 media-type <code>text/html</code>, then the file
131 <code>welcome.gif.html</code> will be associated with the
132 media-type <code>text/html</code>.</p>
134 <p><a href="#charset-lang">Languages</a> and <a href="#contentencoding">content encodings</a> are treated accumulative, because one can assign
135 more than one language or encoding to a particular resource. For example,
136 the file <code>welcome.html.en.de</code> will be delivered with
137 <code>Content-Language: en, de</code> and <code>Content-Type:
138 text/html</code>.</p>
140 <p>Care should be taken when a file with multiple extensions
141 gets associated with both a <a class="glossarylink" href="../glossary.html#media-type" title="see glossary">media-type</a>
142 and a handler. This will
143 usually result in the request being handled by the module associated
144 with the handler. For example, if the <code>.imap</code>
145 extension is mapped to the handler <code>imap-file</code> (from
146 <code class="module"><a href="../mod/mod_imagemap.html">mod_imagemap</a></code>) and the <code>.html</code> extension is
147 mapped to the media-type <code>text/html</code>, then the file
148 <code>world.imap.html</code> will be associated with both the
149 <code>imap-file</code> handler and <code>text/html</code> media-type.
150 When it is processed, the <code>imap-file</code> handler will be used,
151 and so it will be treated as a <code class="module"><a href="../mod/mod_imagemap.html">mod_imagemap</a></code> imagemap
154 <p>If you would prefer only the last dot-separated part of the
155 filename to be mapped to a particular piece of meta-data, then do
156 not use the <code>Add*</code> directives. For example, if you wish
157 to have the file <code>foo.html.cgi</code> processed as a CGI
158 script, but not the file <code>bar.cgi.html</code>, then instead
159 of using <code>AddHandler cgi-script .cgi</code>, use</p>
161 <div class="example"><h3>Configure handler based on final extension only</h3><pre class="prettyprint lang-config"><FilesMatch "[^.]+\.cgi$">

168 <h2><a name="contentencoding" id="contentencoding">Content encoding</a></h2>
169 <p>A file of a particular <a class="glossarylink" href="../glossary.html#media-type" title="see glossary">media-type</a> can additionally be encoded a
170 particular way to simplify transmission over the Internet.
171 While this usually will refer to compression, such as
172 <code>gzip</code>, it can also refer to encryption, such a
173 <code>pgp</code> or to an encoding such as UUencoding, which is
174 designed for transmitting a binary file in an ASCII (text)
177 <p>The <a href="http://www.ietf.org/rfc/rfc2616.txt">HTTP/1.1
178 RFC</a>, section 14.11 puts it this way:</p>
180 <blockquote cite="http://www.ietf.org/rfc/rfc2616.txt">
181 <p>The Content-Encoding entity-header field is used as a modifier to
182 the media-type. When present, its value indicates what additional
183 content codings have been applied to the entity-body, and thus what
184 decoding mechanisms must be applied in order to obtain the media-type
185 referenced by the Content-Type header field. Content-Encoding is
186 primarily used to allow a document to be compressed without losing
187 the identity of its underlying media type.</p>
190 <p>By using more than one file extension (see <a href="#multipleext">section above about multiple file
191 extensions</a>), you can indicate that a file is of a
192 particular <em>type</em>, and also has a particular
193 <em>encoding</em>. </p>
195 <p>For example, you may have a file which is a Microsoft Word
196 document, which is pkzipped to reduce its size. If the
197 <code>.doc</code> extension is associated with the Microsoft
198 Word file type, and the <code>.zip</code> extension is
199 associated with the pkzip file encoding, then the file
200 <code>Resume.doc.zip</code> would be known to be a pkzip'ed Word
203 <p>Apache sends a <code>Content-encoding</code> header with the
204 resource, in order to tell the client browser about the
207 <pre class="prettyprint lang-config">Content-encoding: pkzip</pre>

210 <div class="section">
211 <h2><a name="charset-lang" id="charset-lang">Character sets and languages</a></h2>
212 <p>In addition to file type and the file encoding,
213 another important piece of information is what language a
214 particular document is in, and in what character set the file
215 should be displayed. For example, the document might be written
216 in the Vietnamese alphabet, or in Cyrillic, and should be
217 displayed as such. This information, also, is transmitted in
220 <p>The character set, language, encoding and mime type are all
221 used in the process of content negotiation (See
222 <code class="module"><a href="../mod/mod_negotiation.html">mod_negotiation</a></code>) to determine
223 which document to give to the client, when there are
224 alternative documents in more than one character set, language,
225 encoding or mime type. All filename extensions associations
226 created with <code class="directive"><a href="#addcharset">AddCharset</a></code>,
227 <code class="directive"><a href="#addencoding">AddEncoding</a></code>, <code class="directive"><a href="#addlanguage">AddLanguage</a></code> and <code class="directive"><a href="#addtype">AddType</a></code> directives
228 (and extensions listed in the <code class="directive"><a href="../mod/mod_mime_magic.html#mimemagicfile">MimeMagicFile</a></code>) participate in this select process.
229 Filename extensions that are only associated using the <code class="directive"><a href="#addhandler">AddHandler</a></code>, <code class="directive"><a href="#addinputfilter">AddInputFilter</a></code> or <code class="directive"><a href="#addoutputfilter">AddOutputFilter</a></code> directives may be included or excluded
230 from matching by using the <code class="directive"><a href="#multiviewsmatch">MultiviewsMatch</a></code> directive.</p>
232 <h3><a name="charset" id="charset">Charset</a></h3>
233 <p>To convey this further information, Apache optionally sends
234 a <code>Content-Language</code> header, to specify the language
235 that the document is in, and can append additional information
236 onto the <code>Content-Type</code> header to indicate the
237 particular character set that should be used to correctly
238 render the information.</p>
240 <div class="example"><p><code>
241 Content-Language: en, fr
242 Content-Type: text/plain; charset=ISO-8859-1
245 <p>The language specification is the two-letter abbreviation

712 <p><code class="directive">MultiviewsMatch</code> permits three different
713 behaviors for <a href="mod_negotiation.html">mod_negotiation</a>'s
714 Multiviews feature. Multiviews allows a request for a file,
715 <em>e.g.</em> <code>index.html</code>, to match any negotiated
716 extensions following the base request, <em>e.g.</em>
717 <code>index.html.en</code>, <code>index.html.fr</code>, or
718 <code>index.html.gz</code>.</p>
720 <p>The <code>NegotiatedOnly</code> option provides that every extension
721 following the base name must correlate to a recognized
722 <code class="module"><a href="../mod/mod_mime.html">mod_mime</a></code> extension for content negotiation, <em>e.g.</em>
723 Charset, Content-Type, Language, or Encoding. This is the strictest
724 implementation with the fewest unexpected side effects, and is the
725 default behavior.</p>
727 <p>To include extensions associated with Handlers and/or Filters,
728 set the <code class="directive">MultiviewsMatch</code> directive to either
729 <code>Handlers</code>, <code>Filters</code>, or both option keywords.
730 If all other factors are equal, the smallest file will be served,
731 <em>e.g.</em> in deciding between <code>index.html.cgi</code> of 500
732 bytes and <code>index.html.pl</code> of 1000 bytes, the <code>.cgi</code>
733 file would win in this example. Users of <code>.asis</code> files
734 might prefer to use the Handler option, if <code>.asis</code> files are
735 associated with the <code>asis-handler</code>.</p>
737 <p>You may finally allow <code>Any</code> extensions to match, even if
738 <code class="module"><a href="../mod/mod_mime.html">mod_mime</a></code> doesn't recognize the extension. This can cause
739 unpredictable results, such as serving .old or .bak files the webmaster

836 <p>The <code class="directive">RemoveHandler</code> directive removes any
837 handler associations for files with the given extensions. This allows
838 <code>.htaccess</code> files in subdirectories to undo any
839 associations inherited from parent directories or the server
840 config files. An example of its use might be:</p>
842 <div class="example"><h3>/foo/.htaccess:</h3><pre class="prettyprint lang-config">AddHandler server-parsed .html</pre>
845 <div class="example"><h3>/foo/bar/.htaccess:</h3><pre class="prettyprint lang-config">RemoveHandler .html</pre>
848 <p>This has the effect of returning <code>.html</code> files in
849 the <code>/foo/bar</code> directory to being treated as normal
850 files, rather than as candidates for parsing (see the <code class="module"><a href="../mod/mod_include.html">mod_include</a></code> module).</p>
852 <p>The <var>extension</var> argument is case-insensitive and can
853 be specified with or without a leading dot.</p>

986 configuration file. <var>File-path</var> is relative to the
987 <code class="directive"><a href="../mod/core.html#serverroot">ServerRoot</a></code>. This file sets
988 the default list of mappings from filename extensions to content
989 types. Most administrators use the <code>mime.types</code> file
990 provided by their OS, which associates common filename
991 extensions with the official list of IANA registered media types
992 maintained at <a href="http://www.iana.org/assignments/media-types/index.html">http://www.iana.org/assignments/media-types/index.html</a>
993 as well as a large number of unofficial types. This
994 simplifies the <code>httpd.conf</code> file by providing the
995 majority of media-type definitions, and may be overridden by
996 <code class="directive"><a href="#addtype">AddType</a></code> directives as
997 needed. You should not edit the <code>mime.types</code> file,
998 because it may be replaced when you upgrade your server.</p>
1000 <p>The file contains lines in the format of the arguments to
1001 an <code class="directive"><a href="#addtype">AddType</a></code> directive:</p>
1003 <div class="example"><p><code>
1004 <var>media-type</var> [<var>extension</var>] ...
1007 <p>The case of the extension does not matter. Blank lines, and lines
1008 beginning with a hash character (<code>#</code>) are ignored.
1009 Empty lines are there for completeness (of the mime.types file).
1010 Apache httpd can still determine these types with <code class="module"><a href="../mod/mod_mime_magic.html">mod_mime_magic</a></code>.
1014 Please do <strong>not</strong> send requests to the Apache HTTP
1015 Server Project to add any new entries in the distributed
1016 <code>mime.types</code> file unless (1) they are already
1017 registered with IANA, and (2) they use widely accepted,
1018 non-conflicting filename extensions across platforms.
1019 <code>category/x-subtype</code> requests will be automatically
1020 rejected, as will any new two-letter extensions as they will
1021 likely conflict later with the already crowded language and
1022 character set namespace.
