A dead simple reverse HTTP proxy. Not intended for production usage, just a learning experience in Haskell.

Fire up the server, ensuring that you have a backend server running on port 3000 (currently hardcoded)

stack build
stack exec proxy-exe 4000

and fire a HTTP request at it.

curl http://localhost:4000/example/path

Currently has no HTTP-specific dependencies:

• network
• attoparsec
• bytestring
• HUnit (for testing)

To be added in no particular order (if I feel like it)

• Config files - apache nginx compatible is a good starting point for features
• Benchmarking - compare to mighty to see how much room for improvement there is (http://www.mew.org/~kazu/proj/mighttpd/en/)
• Multiple backend servers with load balancing algorithm
• Logging
• Header replacement
• Timeouts (send back 504)
