__________________________________________________________________________________________________________________________________________________

NAME

       Ns_AbsoluteUrl, Ns_ParseUrl, Ns_RelativeUrl, Ns_SkipUrl - URL manipulation routines

SYNOPSIS

       #include "ns.h"

       int
       Ns_AbsoluteUrl(Ns_DString *pds, char *url, char *baseurl)

       int
       Ns_ParseUrl(char *url, char **pprotocol, char **phost,
		   char **pport, char **ppath, char **ptail)

       char *
       Ns_RelativeUrl(char *url, char *location)

       char *
       Ns_SkipUrl(Ns_Request *request, int n)
_________________________________________________________________

DESCRIPTION

       Ns_AbsoluteUrl(pds, url, baseurl)

	      Construct an URL based on baseurl but with as many parts of the incomplete url as possible. Return NS_OK or NS_ERROR.

       Ns_ParseUrl(url, pprotocol, phost, pport, ppath, ptail)

	      Parse a URL into its component parts. Pointers to the protocol, host, port, path, and "tail" (last path element) will be set by ref-
	      erence in the passed-in pointers. The passed-in url will be modified.

       Ns_RelativeUrl(url, location)

	      If the url passed in is for this server, then the initial part of the URL is stripped off. e.g.,	on  a  server  whose  location	is
	      http://www.foo.com,  Ns_RelativeUrl  of  "http://www.foo.com/hello" will return "/hello".  Returns a pointer to the beginning of the
	      relative url in the passed-in url, or NULL if error. Will set errno on error.

       Ns_SkipUrl(request, n)

	      Return a pointer n elements into the request's url.
