No indication of where the - redirection came from was provided.</p> - - - <h3>New behavior</h3> - - - <p>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.</p> - - <p>If the ErrorDocument specifies a local redirect to a CGI - script, the script should include a "<code>Status:</code>" - 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> - - <div class="example"><p><code> - ... <br /> - print "Content-type: text/html\n"; <br /> - printf "Status: %s Condition Intercepted\n", $ENV{"REDIRECT_STATUS"}; <br /> - ... - </code></p></div> - - <p>If the script is dedicated to handling a particular error - condition, such as <code>404 Not Found</code>, it can - use the specific code and error text instead.</p> - - <p>Note that the script <em>must</em> emit an appropriate - <code>Status:</code> header (such as <code>302 Found</code>), if the - response contains a <code>Location:</code> header (in order to issue a - client side redirect). Otherwise the <code>Location:</code> header may - have no effect.</p> - - </div></div> -<div class="bottomlang"> -<p><span>Available Languages: </span><a href="./en/custom-error.html" title="English"> en </a> | -<a href="./es/custom-error.html" hreflang="es" rel="alternate" title="Español"> es </a> | -<a href="./fr/custom-error.html" hreflang="fr" rel="alternate" title="Français"> fr </a> | -<a href="./ja/custom-error.html" hreflang="ja" rel="alternate" title="Japanese"> ja </a> | -<a href="./ko/custom-error.html" hreflang="ko" rel="alternate" title="Korean"> ko </a> | -<a href="./tr/custom-error.html" hreflang="tr" rel="alternate" title="Türkçe"> tr </a></p> -</div><div id="footer"> -<p class="apache">Copyright 2009 The Apache Software Foundation.<br />Licensed under the <a href="http://www.apache.org/licenses/LICENSE-2.0">Apache License, Version 2.0</a>.</p> -<p class="menu"><a href="./mod/">Modules</a> | <a href="./mod/directives.html">Directives</a> | <a href="./faq/">FAQ</a> | <a href="./glossary.html">Glossary</a> | <a href="./sitemap.html">Sitemap</a></p></div> -</body></html>
