RE: Citrix Netscaler Rewrite Issue

My understanding is that everything after the question mark is used to specify which application for Oracle Application 
Express to load. For example, /pls/apex/f?p=103:1 and /pls/apex/f?p=102 would load two completely unrelated 
applications. Because of this, I need the full URL passed along. In the past, I've used an index.html file to redirect 
users to the proper URL. Since I'm migrating from an Apache server running as a reverse proxy to a Netscaler appliance, 
this approach is no longer feasible.

I have a Citrix Netscaler appliance (v10.0) and I would like to 
rewrite a URL - essentially when someone visits 
www.example.com<http://www.example.com>, I would like to redirect them 

This seems to work well enough until I get to the question mark, at which point things fall  apart.

"The requested URL /pls/apex/f was not found on this server."

I don't think the problem is with the Netscaler or your escaping; I think that whatever's serving www.example.com 
doesn't have a page for /pls/apex/f and is quite correctly telling you this.

The part after the question mark is called the "query string", and it's (usually) used to communicate parameters to a 
page - a page which must already exist (except in very specific circumstances), without the query string.

What happens if you "curl -v www.example.com"? Do you see the 30[23] redirect coming back? If so, it's a server-side 
problem and not an issue with the appliance.
