GTM HTTP Fetcher makes it easy for Cocoa applications to perform http operations. The fetcher is implemented as a wrapper on NSURLConnection, so its behavior is asynchronous and uses operating-system settings on iOS and Mac OS X.

NOTE: Because NSURLConnection is deprecated as of iOS 9 and OS X 10.11, this class has been superseded by GTMSessionFetcher.

Features include:

• Simple to build; only one source/header file pair is required
• Simple to use: takes just two lines of code to fetch a request
• Callbacks are delegate/selector pairs or blocks
• Flexible cookie storage
• Caching of ETagged responses, reducing overhead of redundant fetches
• Automatic retry on errors, with exponential backoff
• Support for generating multipart MIME upload streams
• Easy, convenient logging of http requests and responses
• Fully independent of other projects
