- <DD>Additional functionality. Allows webmasters to configure the response of
- Apache to some error or problem.

- <P>Customizable responses can be defined to be activated in the
- event of a server detected error or problem.

- <P>e.g. if a script crashes and produces a "500 Server Error"
- response, then this response can be replaced with either some
- friendlier text or by a redirection to another URL (local or
- external).
-
- <P>
-
-<DT>Old behavior
-
- <DD>NCSA httpd 1.3 would return some boring old error/problem message
- which would often be meaningless to the user, and would provide no
- means of logging the symptoms which caused it.<BR>
-
- <P>
-
-<DT>New behavior
-
- <DD>The server can be asked to;
- <OL>
- <LI>Display some other text, instead of the NCSA hard coded messages, or
- <LI>redirect to a local URL, or
- <LI>redirect to an external URL.
- </OL>
-
- <P>Redirecting to another URL can be useful, but only if some information
- can be passed which can then be used to explain and/or log the error/problem
- more clearly.
-
- <P>To achieve this, Apache will define new CGI-like environment
- variables, e.g.
-
- <blockquote><code>
-REDIRECT_HTTP_ACCEPT=*/*, image/gif, image/x-xbitmap, image/jpeg <br>
-REDIRECT_HTTP_USER_AGENT=Mozilla/1.1b2 (X11; I; HP-UX A.09.05 9000/712) <br>
-REDIRECT_PATH=.:/bin:/usr/local/bin:/etc <br>
-REDIRECT_QUERY_STRING= <br>
-REDIRECT_REMOTE_ADDR=121.345.78.123 <br>
-REDIRECT_REMOTE_HOST=ooh.ahhh.com <br>
-REDIRECT_SERVER_NAME=crash.bang.edu <br>
-REDIRECT_SERVER_PORT=80 <br>
-REDIRECT_SERVER_SOFTWARE=Apache/0.8.15 <br>
-REDIRECT_URL=/cgi-bin/buggy.pl <br>
- </code></blockquote>
-
- <P>note the <code>REDIRECT_</code> prefix.
-
- <P>At least <code>REDIRECT_URL</code> and <code>REDIRECT_QUERY_STRING</code> will
- be passed to the new URL (assuming it's a cgi-script or a cgi-include). The
- other variables will exist only if they existed prior to the error/problem.
- <b>None</b> of these will be set if your ErrorDocument is an
- <i>external</i> redirect (i.e. anything starting with a protocol name
- like <code>http:</code>, even if it refers to the same host as the
- server).<p>
-
-<DT>Configuration
-
- <DD> Use of "ErrorDocument" is enabled for .htaccess files when the
- <A HREF="mod/core.html#allowoverride">"FileInfo" override</A> is allowed.
-
- <P>Here are some examples...
-
- <blockquote><code>
-ErrorDocument 500 /cgi-bin/crash-recover <br>
-ErrorDocument 500 "Sorry, our script crashed. Oh dear<br>
-ErrorDocument 500 http://xxx/ <br>
-ErrorDocument 404 /Lame_excuses/not_found.html <br>
-ErrorDocument 401 /Subscription/how_to_subscribe.html
- </code></blockquote>
-
- <P>The syntax is,
-
- <P><code><A HREF="mod/core.html#errordocument">ErrorDocument</A></code>
-<3-digit-code> action
-
- <P>where the action can be,
-
- <OL>
- <LI>Text to be displayed. Prefix the text with a quote ("). Whatever
- follows the quote is displayed. <em>Note: the (") prefix isn't
- displayed.</em>
-
- <LI>An external URL to redirect to.
-
- <LI>A local URL to redirect to.
-
- </OL>

-<h2>Custom error responses and redirects</H2>
-
-<DL>
-
-<DT>Purpose
-
- <DD>Apache's behavior to redirected URLs has been modified so that additional
- environment variables are available to a script/server-include.<p>
-
-<DT>Old behavior
-
- <DD>Standard CGI vars were made available to a script which has been
- redirected to. No indication of where the redirection came from was provided.
-
- <p>
-
-<DT>New behavior
- <DD>
-
-A new batch of environment variables will be initialized for use by a
-script which has been redirected to. Each new variable will have the
-prefix <code>REDIRECT_</code>. <code>REDIRECT_</code> environment
-variables are created from the CGI environment variables which existed
-prior to the redirect, they are renamed with a <code>REDIRECT_</code>
-prefix, i.e. <code>HTTP_USER_AGENT</code> becomes
-<code>REDIRECT_HTTP_USER_AGENT</code>. In addition to these new
-variables, Apache will define <code>REDIRECT_URL</code> and
-<code>REDIRECT_STATUS</code> to help the script trace its origin.
-Both the original URL and the URL being redirected to can be logged in
-the access log.
