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!)
