HTTPRequest and save the file locally into iPad/iPhone

how do i do a HTTPRequest and then save the File locally into the iPad/iPhone. Im working with the simulator right now 开发者_开发问答so is it possible to emulate the local data storage?

Yep, this is really easy to do, and I wrote another answer on how to do it: How to download files directly to disk on the iPhone os?

ASIHTTPRequest might also come in handy here as an intelligent wrapper to HTTP functionality:
