NSURL/NSURLRequest for a Proxy Request

Question

I'm trying to rewrite a NSURLRequest (for, say, "http://www.google.com") into a proxy request (for, say, a proxy of 'myproxy.com:3333'. I can't seem to accomplish this with NSURL. Any suggestions?
Based on the HTTP specification, the request to a proxy looks like:
bq. GET http://www.google.com/index.html HTTP/1.0
The path has a full URI which allows the proxy server to determine the destination. A regular request (to www.google.com) would look like
GET /index.hml HTTP/1.0
Programmatically, this could be as simple as (using '{' to avoid '[' wiki formatting):
{{NSURL alloc} initWithScheme: @"http" host: @"myproxy.com:3333" path: @"http://www.google.com/index.html"}
unfortunately NSURL raises an exception rejecting the path. Trying as:
{NSURL URLWithString: @"http://myproxy.com:3333/http://www.google.com/index.html"}
fails as well because the request becomes
GET /http://www.google.com/index.hmtl HTTP/1.0
and the leading '/' (before 'http') causes the proxy server to reject the URI.

Wrap your code between two lines of
[[NSURL alloc] initWithScheme: @"http" host: @"myproxy.com:3333" path: @"http://www.google.com/index.html"]
I think what you are supposed to do is compose the URL with the full path and then send it over a connection to your proxy server.
