These settings can be used to bring in files outside of the document root (like Apache's Alias or AliasMatch directives), to protect a particular directory using authorization realms, or to block or restrict access to a particular directory within the document root.</p> </article> </div>
<div class="helpitem"><article class="ls-helpitem"><div><header id="expuri"><h3>URI<span class="ls-permlink"><a href="#expuri"></a></span><span class="top"><a href="#top">⇑</a></span></h3></header></div><h4>Description</h4><p>Specifies the URI for this context.</p> <h4>Syntax</h4><p>The URI can be a plain URI (starting with "/") or a Perl compatible regular expression URI (starting with "exp:"). If a plain URI ends with a "/", then this context will include all sub-URIs under this URI. If the context maps to a directory on the file system, a trailing "/" must be added.</p> <h4>See Also</h4><p class="ls-text-small"><span class="tagl"><a href="#location">Location</a></span></p> </article> </div>
<div class="helpitem"><article class="ls-helpitem"><div><header id="location"><h3>Location<span class="ls-permlink"><a href="#location"></a></span><span class="top"><a href="#top">⇑</a></span></h3></header></div><h4>Description</h4><p>Specifies the corresponding location of this context in the file system.<br/><br/> Default value: $DOC_ROOT + <span class="tagl"><a href="#expuri">URI</a></span></p> <h4>Syntax</h4><p>It can be an absolute path or path relative to $SERVER_ROOT, $VH_ROOT, or $DOC_ROOT. $DOC_ROOT is the default relative path, and can be omitted.<br/><br/> If the <span class="tagl"><a href="#expuri">URI</a></span> is a regular expression, then the matched sub-string can be used to form the "Root" string. The matched sub-string can be referenced with the values "$1" - "$9". "$0" and "&" can be used to reference the whole matched string. Additionally, a query string can be set by appending a "?" followed by the query string. Be careful. "&" should be escaped as "\&" in the query string.</p> <h4>Example</h4><div class="ls-example">A plain URI like <span class="val">/examples/</span> with <span class="tagl"><a href="#location">Location</a></span> set to <span class="val">/home/john/web_examples</span> will map the request "/examples/foo/bar.html" to file "/home/john/web_examples/foo/bar.html".<br/> To simulate Apache's mod_userdir, set URI to <span class="val">exp: ^/~([A-Za-z0-9]+)(.*)</span>, set <span class="tagl"><a href="#location">Location</a></span> to <span class="val">/home/$1/public_html$2</span>.
