NAME¶

Ns_ConnRedirect - Internally redirect a request to a new local url

SYNOPSIS¶

#include "ns.h"

int
Ns_ConnRedirect(conn, url)

ARGUMENTS¶

Ns_Conn conn (in)

Pointer to open connection.

char *url (in)

Pointer to string of local url.

DESCRIPTION¶

This routine can be used to internally redirect to a new, local url on the server. The url paramter specifies a path relative to the server, i.e., without the leading "http://host:port" portion. The server will reset the Ns_Request structure in the open connection pointed to by conn and restart connection handling, including authorization checks. The result is a standard AOLserver request procedure result code, either from an underlying call to Ns_ConnRunRequest or the result of one of the authorization response routines such as Ns_ConnReturnForbidden. Filter callbacks, if any, are not run again with the updated connection.

The Ns_ConnRedirect routine is used internally in the server to support the basic file serving code (i.e., "fastpath") to redirect to specific files when a directory is opened and by the Ns_RegisterRedirect routine to map standard reponse routines to user-provided local url's.

EXAMPLE¶

The following example demonstrates redirecting to an ADP help page within a custom C-level request callback whenever a ?help=topic query argument is present:

	int
	MyRequest(void *arg, Ns_Conn *conn)
	{
		Ns_Set *query = Ns_ConnGetQuery(conn);
		/* Redirect to help.adp for /myrequest?help=topic calls. */
		if (Ns_SetGet(query, "help")) != NULL) {
			return Ns_ConnReturnRedirect(conn, "/help.adp");
		}
		...  handle non-help requests ...
	}
