The <code class="directive"><a href="#alias">Alias</a></code> and <code class="directive"><a href="#scriptalias">ScriptAlias</a></code> directives are used to map between URLs and filesystem paths. This allows for content which is not directly under the <code class="directive"><a href="../mod/core.html#documentroot">DocumentRoot</a></code> served as part of the web document tree. The <code class="directive"><a href="#scriptalias">ScriptAlias</a></code> directive has the additional effect of marking the target directory as containing only CGI scripts.</p> <p>The <code class="directive"><a href="#redirect">Redirect</a></code> directives are used to instruct clients to make a new request with a different URL. They are often used when a resource has moved to a new location.</p> <p><code class="module"><a href="../mod/mod_alias.html">mod_alias</a></code> is designed to handle simple URL manipulation tasks.

But when multiple Aliases or Redirects occur in the same context (for example, in the same <code class="directive"><a href="../mod/core.html#virtualhost"><VirtualHost></a></code> section) they are processed in a particular order.</p> <p>First, all Redirects are processed before Aliases are processed, and therefore a request that matches a <code class="directive"><a href="#redirect">Redirect</a></code> or <code class="directive"><a href="#redirectmatch">RedirectMatch</a></code> will never have Aliases applied. Second, the Aliases and Redirects are processed in the order they appear in the configuration files, with the first match taking precedence.</p> <p>For this reason, when two or more of these directives apply to the same sub-path, you must list the most specific path first in order for all the directives to have an effect. For example, the following configuration will work as expected:</p> <div class="example"><p><code> Alias /foo/bar /baz<br /> Alias /foo /gaq </code></p></div> <p>But if the above two directives were reversed in order, the <code>/foo</code> <code class="directive"><a href="#alias">Alias</a></code> would always match before the <code>/foo/bar</code> <code class="directive"><a href="#alias">Alias</a></code>, so the latter directive would be ignored.</p> </div> <div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div> <div class="directive-section"><h2><a name="Alias" id="Alias">Alias</a> <a name="alias" id="alias">Directive</a></h2> <table class="directive"> <tr><th><a href="directive-dict.html#Description">Description:</a></th><td>Maps URLs to filesystem locations</td></tr> <tr><th><a href="directive-dict.html#Syntax">Syntax:</a></th><td><code>Alias <var>URL-path</var> <var>file-path</var>|<var>directory-path</var></code></td></tr> <tr><th><a href="directive-dict.html#Context">Context:</a></th><td>server config, virtual host</td></tr> <tr><th><a href="directive-dict.html#Status">Status:</a></th><td>Base</td></tr> <tr><th><a href="directive-dict.html#Module">Module:</a></th><td>mod_alias</td></tr> </table> <p>The <code class="directive">Alias</code> directive allows documents to be stored in the local filesystem other than under the <code class="directive"><a href="../mod/core.html#documentroot">DocumentRoot</a></code>. URLs with a (%-decoded) path beginning with <var>URL-path</var> will be mapped to local files beginning with <var>directory-path</var>. The <var>URL-path</var> is case-sensitive, even on case-insensitive file systems.</p> <div class="example"><h3>Example:</h3><p><code> Alias /image /ftp/pub/image </code></p></div> <p>A request for <code>http://example.com/image/foo.gif</code> would cause the server to return the file <code>/ftp/pub/image/foo.gif</code>. Only complete path segments are matched, so the above alias would not match a request for <code>http://example.com/imagefoo.gif</code>. For more complex matching using regular expressions, see the <code class="directive"><a href="#aliasmatch">AliasMatch</a></code> directive.</p> <p>Note that if you include a trailing / on the <var>URL-path</var> then the server will require a trailing / in order to expand the alias. That is, if you use</p> <div class="example"><p><code> Alias /icons/ /usr/local/apache/icons/ </code></p></div> <p>then the URL <code>/icons</code> will not be aliased, as it lacks that trailing /. Likewise, if you omit the slash on the <var>URL-path</var> then you must also omit it from the <var>file-path</var>.</p> <p>Note that you may need to specify additional <code class="directive"><a href="../mod/core.html#directory"><Directory></a></code> sections which cover the <em>destination</em> of aliases. Aliasing occurs before <code class="directive"><a href="../mod/core.html#directory"><Directory></a></code> sections are checked, so only the destination of aliases are affected. (Note however <code class="directive"><a href="../mod/core.html#location"><Location></a></code> sections are run through once before aliases are performed, so they will apply.)</p> <p>In particular, if you are creating an <code>Alias</code> to a directory outside of your <code class="directive"><a href="../mod/core.html#documentroot">DocumentRoot</a></code>, you may need to explicitly permit access to the target directory.</p> <div class="example"><h3>Example:</h3><p><code> Alias /image /ftp/pub/image<br /> <Directory /ftp/pub/image><br /> <span class="indent"> Order allow,deny<br /> Allow from all<br /> </span> </Directory> </code></p></div> <p>Any number of slashes in the <var>URL-path</var> parameter matches any number of slashes in the requested URL-path.</p> </div> <div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div> <div class="directive-section"><h2><a name="AliasMatch" id="AliasMatch">AliasMatch</a> <a name="aliasmatch" id="aliasmatch">Directive</a></h2> <table class="directive"> <tr><th><a href="directive-dict.html#Description">Description:</a></th><td>Maps URLs to filesystem locations using regular expressions</td></tr> <tr><th><a href="directive-dict.html#Syntax">Syntax:</a></th><td><code>AliasMatch <var>regex</var> <var>file-path</var>|<var>directory-path</var></code></td></tr> <tr><th><a href="directive-dict.html#Context">Context:</a></th><td>server config, virtual host</td></tr> <tr><th><a href="directive-dict.html#Status">Status:</a></th><td>Base</td></tr> <tr><th><a href="directive-dict.html#Module">Module:</a></th><td>mod_alias</td></tr> </table> <p>This directive is equivalent to <code class="directive"><a href="#alias">Alias</a></code>, but makes use of <a class="glossarylink" href="../glossary.html#regex" title="see glossary">regular expressions</a>, instead of simple prefix matching. The supplied regular expression is matched against the URL-path, and if it matches, the server will substitute any parenthesized matches into the given string and use it as a filename. For example, to activate the <code>/icons</code> directory, one might use:</p> <div class="example"><p><code> AliasMatch ^/icons(.*) /usr/local/apache/icons$1 </code></p></div> <p>The full range of <a class="glossarylink" href="../glossary.html#regex" title="see glossary">regular expression</a> power is available. For example, it is possible to construct an alias with case-insensitive matching of the URL-path:</p> <div class="example"><p><code> AliasMatch (?i)^/image(.*) /ftp/pub/image$1 </code></p></div> <p>One subtle difference between <code class="directive"><a href="#alias">Alias</a></code> and <code class="directive"><a href="#aliasmatch">AliasMatch</a></code> is that <code class="directive"><a href="#alias">Alias</a></code> will automatically copy any additional part of the URI, past the part that matched, onto the end of the file path on the right side, while <code class="directive"><a href="#aliasmatch">AliasMatch</a></code> will not. This means that in almost all cases, you will want the regular expression to match the entire request URI from beginning to end, and to use substitution on the right side.</p> <p>In other words, just changing <code class="directive"><a href="#alias">Alias</a></code> to <code class="directive"><a href="#aliasmatch">AliasMatch</a></code> will not have the same effect. At a minimum, you need to add <code>^</code> to the beginning of the regular expression and add <code>(.*)$</code> to the end, and add <code>$1</code> to the end of the replacement.</p> <p>For example, suppose you want to replace this with AliasMatch:</p> <div class="example"><p><code> Alias /image/ /ftp/pub/image/ </code></p></div> <p>This is NOT equivalent - don't do this! This will send all requests that have /image/ anywhere in them to /ftp/pub/image/:</p> <div class="example"><p><code> AliasMatch /image/ /ftp/pub/image/ </code></p></div> <p>This is what you need to get the same effect:</p> <div class="example"><p><code> AliasMatch ^/image/(.*)$ /ftp/pub/image/$1 </code></p></div> <p>Of course, there's no point in using <code class="directive"><a href="#aliasmatch">AliasMatch</a></code> where <code class="directive"><a href="#alias">Alias</a></code> would work. <code class="directive"><a href="#aliasmatch">AliasMatch</a></code> lets you do more complicated things. For example, you could serve different kinds of files from different directories:</p> <div class="example"><p><code> AliasMatch ^/image/(.*)\.jpg$ /files/jpg.images/$1.jpg<br /> AliasMatch ^/image/(.*)\.gif$ /files/gif.images/$1.gif </code></p></div> <p>Multiple leading slashes in the requested URL are discarded by the server before directives from this module compares against the requested URL-path. </p> </div> <div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div> <div class="directive-section"><h2><a name="Redirect" id="Redirect">Redirect</a> <a name="redirect" id="redirect">Directive</a></h2> <table class="directive"> <tr><th><a href="directive-dict.html#Description">Description:</a></th><td>Sends an external redirect asking the client to fetch a different URL</td></tr> <tr><th><a href="directive-dict.html#Syntax">Syntax:</a></th><td><code>Redirect [<var>status</var>] <var>URL-path</var> <var>URL</var></code></td></tr> <tr><th><a href="directive-dict.html#Context">Context:</a></th><td>server config, virtual host, directory, .htaccess</td></tr> <tr><th><a href="directive-dict.html#Override">Override:</a></th><td>FileInfo</td></tr> <tr><th><a href="directive-dict.html#Status">Status:</a></th><td>Base</td></tr> <tr><th><a href="directive-dict.html#Module">Module:</a></th><td>mod_alias</td></tr> <tr><th><a href="directive-dict.html#Compatibility">Compatibility:</a></th><td>Support for specifying a URL-path as the final argument was added in Apache HTTP Server 2.2.6</td></tr> </table> <p>The Redirect directive maps an old URL into a new one by asking the client to refetch the resource at the new location.</p> <p>The old <em>URL-path</em> is a case-sensitive (%-decoded) path beginning with a slash. A relative path is not allowed. The new <em>URL</em> should be an absolute URL beginning with a scheme and hostname. In Apache HTTP Server 2.2.6 and later, a URL-path beginning with a slash may also be used, in which case the scheme and hostname of the current server will be added.</p> <p>Then any request beginning with <em>URL-path</em> will return a redirect request to the client at the location of the target <em>URL</em>. Additional path information beyond the matched <em>URL-path</em> will be appended to the target URL.</p> <div class="example"><h3>Example:</h3><p><code> Redirect /service http://foo2.example.com/service </code></p></div> <p>If the client requests <code>http://example.com/service/foo.txt</code>, it will be told to access <code>http://foo2.example.com/service/foo.txt</code> instead. Only complete path segments are matched, so the above example would not match a request for <code>http://example.com/servicefoo.txt</code>. For more complex matching using regular expressions, see the <code class="directive"><a href="#redirectmatch">RedirectMatch</a></code> directive.</p> <div class="note"><h3>Note</h3> <p>Redirect directives take precedence over Alias and ScriptAlias directives, irrespective of their ordering in the configuration file.</p></div> <p>If no <var>status</var> argument is given, the redirect will be "temporary" (HTTP status 302). This indicates to the client that the resource has moved temporarily. The <var>status</var> argument can be used to return other HTTP status codes:</p> <dl> <dt>permanent</dt> <dd>Returns a permanent redirect status (301) indicating that the resource has moved permanently.</dd> <dt>temp</dt> <dd>Returns a temporary redirect status (302). This is the default.</dd> <dt>seeother</dt> <dd>Returns a "See Other" status (303) indicating that the resource has been replaced.</dd> <dt>gone</dt> <dd>Returns a "Gone" status (410) indicating that the resource has been permanently removed. When this status is used the <var>URL</var> argument should be omitted.</dd> </dl> <p>Other status codes can be returned by giving the numeric status code as the value of <var>status</var>. If the status is between 300 and 399, the <var>URL</var> argument must be present, otherwise it must be omitted.
