+<h3>Summary</h3>
+
+ <p>The directives contained in this module allow for manipulation
+ and control of URLs as requests arrive at the server. 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>When the <code class="directive"><a href="#alias">Alias</a></code>,
+ <code class="directive"><a href="#scriptalias">ScriptAlias</a></code> and
+ <code class="directive"><a href="#redirect">Redirect</a></code> directives are used
+ within a <code class="directive"><a href="../mod/core.html#location">&lt;Location&gt;</a></code>
+ or <code class="directive"><a href="../mod/core.html#locationmatch">&lt;LocationMatch&gt;</a></code>
+ section, <a href="../expr.html">expression syntax</a> can be used
+ to manipulate the destination path or URL.
+ </p>
+
+ <p><code class="module"><a href="../mod/mod_alias.html">mod_alias</a></code> is designed to handle simple URL
+ manipulation tasks. For more complicated tasks such as
+ manipulating the query string, use the tools provided by
+ <code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code>.</p>

+<h2><a name="order" id="order">Order of Processing</a></h2>
+
+ <p>Aliases and Redirects occurring in different contexts are processed
+ like other directives according to standard <a href="../sections.html#mergin">merging rules</a>. 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">&lt;VirtualHost&gt;</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>
+
+ <pre class="prettyprint lang-config">Alias "/foo/bar" "/baz"
+Alias "/foo" "/gaq"</pre>
+
+
+ <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>
+
+ <p>When the <code class="directive"><a href="#alias">Alias</a></code>,
+ <code class="directive"><a href="#scriptalias">ScriptAlias</a></code> and
+ <code class="directive"><a href="#redirect">Redirect</a></code> directives are used
+ within a <code class="directive"><a href="../mod/core.html#location">&lt;Location&gt;</a></code>
+ or <code class="directive"><a href="../mod/core.html#locationmatch">&lt;LocationMatch&gt;</a></code>
+ section, these directives will take precedence over any globally
+ defined <code class="directive"><a href="#alias">Alias</a></code>,
+ <code class="directive"><a href="#scriptalias">ScriptAlias</a></code> and
+ <code class="directive"><a href="#redirect">Redirect</a></code> directives.</p>

+
+ <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>
+
+ <pre class="prettyprint lang-config">Alias "/image" "/ftp/pub/image"</pre>
+
+
+ <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>
+
+ <pre class="prettyprint lang-config">Alias "/icons/" "/usr/local/apache/icons/"</pre>
+
+
+ <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">&lt;Directory&gt;</a></code> sections which
+ cover the <em>destination</em> of aliases. Aliasing occurs before
+ <code class="directive"><a href="../mod/core.html#directory">&lt;Directory&gt;</a></code> sections
+ are checked, so only the destination of aliases are affected.
+ (Note however <code class="directive"><a href="../mod/core.html#location">&lt;Location&gt;</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>
+
+ <pre class="prettyprint lang-config">Alias "/image" "/ftp/pub/image"
+&lt;Directory "/ftp/pub/image"&gt;
+ Require all granted
+&lt;/Directory&gt;</pre>
+
+
+ <p>Any number slashes in the <var>URL-path</var> parameter
+ matches any number of slashes in the requested URL-path.</p>
+
+ <p>If the <code class="directive">Alias</code> directive is used within a
+ <code class="directive"><a href="../mod/core.html#location">&lt;Location&gt;</a></code>
+ or <code class="directive"><a href="../mod/core.html#locationmatch">&lt;LocationMatch&gt;</a></code>
+ section the URL-path is omitted, and the file-path is interpreted
+ using <a href="../expr.html">expression syntax</a>.<br />
+ This syntax is available in Apache 2.4.19 and later.</p>
+
+ <pre class="prettyprint lang-config">&lt;Location "/image"&gt;
+ Alias "/ftp/pub/image"
+&lt;/Location&gt;
+&lt;LocationMatch "/error/(?&lt;NUMBER&gt;[0-9]+)"&gt;

+ <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>
+
+ <pre class="prettyprint lang-config">AliasMatch "^/icons(/|$)(.*)" "/usr/local/apache/icons$1$2"</pre>
+
+
+ <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>
+
+ <pre class="prettyprint lang-config">AliasMatch "(?i)^/image(.*)" "/ftp/pub/image$1"</pre>
+
+
+ <p>One subtle difference
+ between <code class="directive"><a href="#alias">Alias</a></code>
+ and <code class="directive"><a href="#aliasmatch">AliasMatch</a></code> is
+ that <code class="directive"><a href="#alias">Alias</a></code> will
+ automatically copy any additional part of the URI, past the part
+ that matched, onto the end of the file path on the right side,
+ while <code class="directive"><a href="#aliasmatch">AliasMatch</a></code> will
+ not. This means that in almost all cases, you will want the
+ regular expression to match the entire request URI from beginning
+ to end, and to use substitution on the right side.</p>
+
+ <p>In other words, just changing
+ <code class="directive"><a href="#alias">Alias</a></code> to
+ <code class="directive"><a href="#aliasmatch">AliasMatch</a></code> will not
+ have the same effect. At a minimum, you need to
+ add <code>^</code> to the beginning of the regular expression
+ and add <code>(.*)$</code> to the end, and add <code>$1</code> to
+ the end of the replacement.</p>
+
+ <p>For example, suppose you want to replace this with AliasMatch:</p>
+
+ <pre class="prettyprint lang-config">Alias "/image/" "/ftp/pub/image/"</pre>
+
+
+ <p>This is NOT equivalent - don't do this! This will send all
+ requests that have /image/ anywhere in them to /ftp/pub/image/:</p>
+
+ <pre class="prettyprint lang-config">AliasMatch "/image/" "/ftp/pub/image/"</pre>
+
+
+ <p>This is what you need to get the same effect:</p>
+
+ <pre class="prettyprint lang-config">AliasMatch "^/image/(.*)$" "/ftp/pub/image/$1"</pre>
+
+
+ <p>Of course, there's no point in
+ using <code class="directive"><a href="#aliasmatch">AliasMatch</a></code>
+ where <code class="directive"><a href="#alias">Alias</a></code> would
+ work. <code class="directive"><a href="#aliasmatch">AliasMatch</a></code> lets
+ you do more complicated things. For example, you could
+ serve different kinds of files from different directories:</p>
+
+ <pre class="prettyprint lang-config">AliasMatch "^/image/(.*)\.jpg$" "/files/jpg.images/$1.jpg"
+AliasMatch "^/image/(.*)\.gif$" "/files/gif.images/$1.gif"</pre>
+
+
+ <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>
+
+

+ <p>The <code class="directive">Redirect</code> 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.</p>
+
+ <p>The new <em>URL</em> may be either an absolute URL beginning
+ with a scheme and hostname, or a URL-path beginning with a slash.
+ In this latter 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>

+ instead. This includes requests with <code>GET</code> parameters, such as

+ <p>The <code class="directive">ScriptAlias</code> directive has the same
+ behavior as the <code class="directive"><a href="#alias">Alias</a></code>
+ directive, except that in addition it marks the target directory
+ as containing CGI scripts that will be processed by <code class="module"><a href="../mod/mod_cgi.html">mod_cgi</a></code>'s cgi-script handler. URLs with a case-sensitive
+ (%-decoded) path beginning with <var>URL-path</var> will be mapped
+ to scripts beginning with the second argument, which is a full
+ pathname in the local filesystem.</p>
+
+ <pre class="prettyprint lang-config">ScriptAlias "/cgi-bin/" "/web/cgi-bin/"</pre>
+
+
+ <p>A request for <code>http://example.com/cgi-bin/foo</code> would cause the
+ server to run the script <code>/web/cgi-bin/foo</code>. This configuration
+ is essentially equivalent to:</p>
+ <pre class="prettyprint lang-config">Alias "/cgi-bin/" "/web/cgi-bin/"
+&lt;Location "/cgi-bin"&gt;
+ SetHandler cgi-script
+ Options +ExecCGI
+&lt;/Location&gt;</pre>
+
+
+ <p><code class="directive">ScriptAlias</code> can also be used in conjunction with
+ a script or handler you have. For example:</p>
+
+ <pre class="prettyprint lang-config">ScriptAlias "/cgi-bin/" "/web/cgi-handler.pl"</pre>
+
+
+ <p>In this scenario all files requested in <code>/cgi-bin/</code> will be
+ handled by the file you have configured, this allows you to use your own custom
+ handler. You may want to use this as a wrapper for CGI so that you can add
+ content, or some other bespoke action.</p>
+
+ <div class="warning">It is safer to avoid placing CGI scripts under the
+ <code class="directive"><a href="../mod/core.html#documentroot">DocumentRoot</a></code> in order to
+ avoid accidentally revealing their source code if the
+ configuration is ever changed. The
+ <code class="directive">ScriptAlias</code> makes this easy by mapping a
+ URL and designating CGI scripts at the same time. If you do
+ choose to place your CGI scripts in a directory already
+ accessible from the web, do not use
+ <code class="directive">ScriptAlias</code>. Instead, use <code class="directive"><a href="../mod/core.html#directory">&lt;Directory&gt;</a></code>, <code class="directive"><a href="../mod/core.html#sethandler">SetHandler</a></code>, and <code class="directive"><a href="../mod/core.html#options">Options</a></code> as in:
+ <pre class="prettyprint lang-config">&lt;Directory "/usr/local/apache2/htdocs/cgi-bin"&gt;
+ SetHandler cgi-script
+ Options ExecCGI
+&lt;/Directory&gt;</pre>
+
+ This is necessary since multiple <var>URL-paths</var> can map
+ to the same filesystem location, potentially bypassing the
+ <code class="directive">ScriptAlias</code> and revealing the source code
+ of the CGI scripts if they are not restricted by a
+ <code class="directive"><a href="../mod/core.html#directory">Directory</a></code> section.</div>
+
+ <p>If the <code class="directive">ScriptAlias</code> directive is used within
+ a <code class="directive"><a href="../mod/core.html#location">&lt;Location&gt;</a></code>
+ or <code class="directive"><a href="../mod/core.html#locationmatch">&lt;LocationMatch&gt;</a></code>
+ section with the URL-path omitted, then the URL parameter will be
+ interpreted using <a href="../expr.html">expression syntax</a>.<br />
+ This syntax is available in Apache 2.4.19 and later.</p>
+
+ <pre class="prettyprint lang-config">&lt;Location "/cgi-bin"&gt;
+ ScriptAlias "/web/cgi-bin/"
+&lt;/Location&gt;
+&lt;LocationMatch "/cgi-bin/errors/(?&lt;NUMBER&gt;[0-9]+)"&gt;
+ ScriptAlias "/web/cgi-bin/errors/%{env:MATCH_NUMBER}.cgi"

+ <p>This directive is equivalent to <code class="directive"><a href="#scriptalias">ScriptAlias</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 standard <code>/cgi-bin</code>, one
+ might use:</p>
+
+ <pre class="prettyprint lang-config">ScriptAliasMatch "^/cgi-bin(.*)" "/usr/local/apache/cgi-bin$1"</pre>
+
+
+ <p>As for AliasMatch, the full range of <a class="glossarylink" href="../glossary.html#rexex" 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>
+
+ <pre class="prettyprint lang-config">ScriptAliasMatch "(?i)^/cgi-bin(.*)" "/usr/local/apache/cgi-bin$1"</pre>
