ns_geturl - Fetch a URL
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.
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.
The functions was deprecated in favor of ns_http.
