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 great at 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.

Basically, if you’re iPhone or Mac app needs to talk to a remote server. This is the fastest and most developer-friendly way to make it happen.

It provides:

• A straightforward interface for submitting data to and fetching data from web servers.
• Download data to memory or directly to a file on disk.
• Submit files on local drives as part of POST data, compatible with the HTML file input mechanism.
• Stream request bodies directly from disk to the server, to conserve memory.
• Resume for partial downloads.
• Easy access to request and response HTTP headers.
• 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, Digest + NTLM authentication support, credentials are automatically re-used for the duration of a session, and can be stored for later in the Keychain.
• Cookie support.
• GZIP support for response data AND request bodies.
• [NEW] Experimental support for Amazon S3.
• [NEW] Supports manual and auto-detected proxies, authenticating proxies, and PAC file auto-configuration.
• Based on NSOperation to make queuing requests and background operation easy.
• Comes with a broad range of unit tests.
