ns_geturl

Overview

Fetch a URL

Syntax

ns_geturl URL ?headersSetIdVar?

Description

This function retrieves the contents of the passed-in URL. 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.

Example

    ns_register_proc GET /wais getwais
    proc getwais { conn context } {
    	ns_return $conn 200 text/html [ns_geturl \
    		http://www.wais.com/]
    }

Notes

This function should be used with caution. If the server is running with 1 thread, and you perform ns_geturl back to the originating server, the server may deadlock.

Also, ns_geturl 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.
