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

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
• Supports upload and download sessions
• Flexible cookie storage
• Automatic retry on errors, with exponential backoff
• Support for generating multipart MIME upload streams
• Easy, convenient logging of http requests and responses
• Supports plug-in authentication such as with GTMAppAuth
• Easily testable; self-mocking
• Automatic rate limiting when created by the GTMSessionFetcherService factory class
• Fully independent of other projects
