<a name="3550">
</a><h4>Overview</h4>
<p><a name="3554">
</a>Fetch a URL</p>
<a name="3556">
</a><h4>Syntax</h4>
<p><a name="3560">
</a><b>ns_geturl</b> <i>URL</i> ?headersSetIdVar?</p>
<a name="3562">
</a><h4>Description</h4>
<p><a name="3564">
</a>This function retrieves the contents of the passed-in <i>URL</i>. If headersSetIdVar is passed in and it is a valid ns_set, then the header information received along with the request is inserted into it.</p>
<a name="3566">
</a><h4>Example</h4>
<pre> <a name="3570"></a>ns_register_proc GET /wais getwais
<a name="3572"></a>proc getwais { conn context } {
<a name="3578"></a> ns_return 200 text/html [ns_geturl \
<a name="3580"></a> http://www.wais.com/]
<a name="3582"></a>}
</pre><p><a name="3584">
</a><h4>Notes</h4>
<p><a name="3588">
</a>This function should be used with caution. If the server is running with 1 thread, and you perform <code>ns_geturl</code> back to the originating server, the server may deadlock.</p>
<p><a name="25922">
</a>Also, <code>ns_geturl</code> does not follow redirects or handle relative URLs. URLs that are server-relative (begin with "/") are translated into filenames, and the content of the file is returned.</p>
