		<h1 align="CENTER">PATH_INFO Changes in the CGI
		Environment</h1>
		<hr />

		<h2><a id="over" name="over">Overview</a></h2>

		<p>As implemented in Apache 1.1.1 and earlier versions, the
		method Apache used to create PATH_INFO in the CGI environment
		was counterintuitive, and could result in crashes in certain
		cases. In Apache 1.2 and beyond, this behavior has changed.
		Although this results in some compatibility problems with
		certain legacy CGI applications, the Apache 1.2 behavior is
		still compatible with the CGI/1.1 specification, and CGI
		scripts can be easily modified (<a href="#compat">see
		below</a>).</p>

		<h2><a id="prob" name="prob">The Problem</a></h2>

		<p>Apache 1.1.1 and earlier implemented the PATH_INFO and
		SCRIPT_NAME environment variables by looking at the filename,
		not the URL. While this resulted in the correct values in many
		cases, when the filesystem path was overloaded to contain path
		information, it could result in errant behavior. For example,
		if the following appeared in a config file:</p>
		<pre>
		Alias /cgi-ralph /usr/local/httpd/cgi-bin/user.cgi/ralph
		</pre>

		<p>In this case, <code>user.cgi</code> is the CGI script, the
		"/ralph" is information to be passed onto the CGI. If this
		configuration was in place, and a request came for
		"<code>/cgi-ralph/script/</code>", the code would set PATH_INFO
		to "<code>/ralph/script</code>", and SCRIPT_NAME to
		"<code>/cgi-</code>". Obviously, the latter is incorrect. In
		certain cases, this could even cause the server to crash.</p>

		<h2><a id="solution" name="solution">The Solution</a></h2>

		<p>Apache 1.2 and later now determine SCRIPT_NAME and PATH_INFO
		by looking directly at the URL, and determining how much of the
		URL is client-modifiable, and setting PATH_INFO to it. To use
		the above example, PATH_INFO would be set to
		"<code>/script</code>", and SCRIPT_NAME to
		"<code>/cgi-ralph</code>". This makes sense and results in no
		server behavior problems. It also permits the script to be
		guaranteed that
		"<code>http://$SERVER_NAME:$SERVER_PORT$SCRIPT_NAME$PATH_INFO</code>"
		will always be an accessible URL that points to the current
		script, something which was not necessarily true with previous
		versions of Apache.</p>

		<p>However, the "<code>/ralph</code>" information from the
		<code>Alias</code> directive is lost. This is unfortunate, but
		we feel that using the filesystem to pass along this sort of
		information is not a recommended method, and a script making
		use of it "deserves" not to work. Apache 1.2b3 and later,
		however, do provide <a href="#compat">a workaround.</a></p>

		<h2><a id="compat" name="compat">Compatibility with Previous
		Servers</a></h2>

		<p>It may be necessary for a script that was designed for
		earlier versions of Apache or other servers to need the
		information that the old PATH_INFO variable provided. For this
		purpose, Apache 1.2 (1.2b3 and later) sets an additional
		variable, FILEPATH_INFO. This environment variable contains the
		value that PATH_INFO would have had with Apache 1.1.1.</p>

		<p>A script that wishes to work with both Apache 1.2 and
		earlier versions can simply test for the existence of
		FILEPATH_INFO, and use it if available. Otherwise, it can use
		PATH_INFO. For example, in Perl, one might use:</p>
		<pre>
		$path_info = $ENV{'FILEPATH_INFO'} \|\| $ENV{'PATH_INFO'};
		</pre>

		<p>By doing this, a script can work with all servers supporting
		the CGI/1.1 specification, including all versions of
		Apache.</p>

		<h1 align="CENTER">Custom error responses</h1>

		<dl>
		<dt>Purpose</dt>

		<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>

		<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>
		</dd>

		<dt>Old behavior</dt>

		<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 />
		</dd>

		<dt>New behavior</dt>

		<dd>
		The server can be asked to;

		<ol>
		<li>Display some other text, instead of the NCSA hard
		coded messages, or</li>

		<li>redirect to a local URL, or</li>

		<li>redirect to an external URL.</li>
		</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>

		<p>To achieve this, Apache will define new CGI-like
		environment variables, <em>e.g.</em></p>

		<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>

		<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. <strong>None</strong> of these will be
		set if your ErrorDocument is an <em>external</em> redirect
		(<em>i.e.</em>, anything starting with a scheme name like
		<code>http:</code>, even if it refers to the same host as
		the server).</p>
		</dd>

		<dt>Configuration</dt>

		<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...</p>

		<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>

		<p><code><a
		href="mod/core.html#errordocument">ErrorDocument</a></code>
		<3-digit-code> action</p>

		<p>where the action can be,</p>

		<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>

		<li>An external URL to redirect to.</li>

		<li>A local URL to redirect to.</li>
		</ol>
		</dd>
		</dl>
		<hr />

		<h2>Custom error responses and redirects</h2>

		<dl>
		<dt>Purpose</dt>

		<dd>Apache's behavior to redirected URLs has been modified so
		that additional environment variables are available to a
		script/server-include.</dd>

		<dt>Old behavior</dt>

		<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.</dd>

		<dt>New behavior</dt>

		<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, <em>i.e.</em>, <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.</dd>
		</dl>

		<p>If the ErrorDocument specifies a local redirect to a CGI
		script, the script should include a "<samp>Status:</samp>"
		header field in its output in order to ensure the propagation
		all the way back to the client of the error condition that
		caused it to be invoked. For instance, a Perl ErrorDocument
		script might include the following:</p>
		<pre>
		:
		print "Content-type: text/html\n";
		printf "Status: %s Condition Intercepted\n", $ENV{"REDIRECT_STATUS"};
		:
		</pre>

		<p>If the script is dedicated to handling a particular error
		condition, such as <samp>404 Not Found</samp>, it can
		use the specific code and error text instead.</p>
