Vista - Creating a 'proxy' redirector

Hi,

We have web application X where I work that allows us to access
documents via a url, for eg, http://hostname/app.cgi?request_dcou...r?password=ner
etc...

What we would like is for our asp.net app Y to make this request (for
the purpose of hiding the above URL) but let web application X hosting
the document to stream the data back to the client.


Is there any functionality to do this in .net?


One idea i had was for the webserver to download the file in chunks
and simply pass the data on to the client, however, i don't want to
put strain on the server so Id rather avoid this. It consumes lots of
memory too.

Thanks in advance
Vince
