ASIHTTPRequest is an easy to use wrapper around the CFNetwork API that makes some of the more tedious aspects of 
communicating with web servers easier. It is written in Objective-C and works in both Mac OS X and iPhone applications.


It is suitable performing basic HTTP requests and interacting with REST-based services (GET / POST / PUT / DELETE). The 
included ASIFormDataRequest subclass makes it easy to submit POST data and files using multipart/form-data.

It provides:
* A straightforward interface for submitting data to and fetching data from webservers
* Download data to memory or directly to a file on disk(i)
* The ability to submit files on local drives as part of POST data, compatible with the HTML file input mechanism
* Easy access to request and response HTTP headers
* Ability for setting up progress delegates (NSProgressIndicators and UIProgressViews) to show information about 
download AND upload progress
* Auto-magic management of upload and download progress indicators for operation queues
* Basic authentication (username and password) support, credentials are automatically for the duration of a session, and 
can be stored for later in the Keychain.
* Cookie support
* Based on NSOperation to make queuing requests and background operation easy
* Basic unit tests (more to come!)
