WebView is primarily about displaying a webpage. It sounds like you aren't
using it for that. So likely no need to pay for the extra overhead, etc.

It sounds like you need to get at the HTTP content itself and pull data out
of that, right? If all you need is the HTTP content you can drop down to
things like Foundation's URL Loading System [1], maybe drop down lower to
CFNetwork [2], or use something like libcurl (as Greg suggested, possibly
the better suggestion depending on your exact needs).

Also make sure to understand the standard HTTP caching so you can avoid
unneeded data loads (note Mac OS X provided HTTP API honor this scheme, so
you likely don't have to do any work of your own).
