http-monad

Monad abstraction for HTTP allowing lazy transfer and non-I/O simulation.

This library implements a monad class with various interesting instances:

• Lazy I/O allows for fetching documents via HTTP on demand

• Non-I/O allows for testing HTTP communication without any IO action

By using this monad you can implement HTTP communication in a very general way. You may add further functionality by adding custom sub-classes.

We inherit all content data types from the HTTP-4000 package, such as String as well as strict and lazy ByteString.
