proxylet Description

Lightweight HTTP reverse proxy built on eventlet proxylet is a Python module that implements a lightweight reverse proxy for HTTP, using non-blocking IO based on the eventlet module. It aims to do as little as possible while supporting simple request/response rewriting and being compatible with HTTP keep-alive.Basic operation is via the 'serve' function, which will bind to the specified host and port and start accepting incoming HTTP requests:proxylet.serve(host,port,mapper)Here 'mapper' is a function taking a proxylet.streams.HTTPRequest object, and returning either None (for '404 Not Found') or a 3-tuple giving the destination host, destination port, and a rewriter object.The rewriter can be any callable that takes request and response streams as arguments and returns wrapped versions of them, but it will most likely be a subclass of proxylet.relocate.Relocator. This class has the necessary logic to rewrite the request for proxying.As an example of the available functionality, this mapping function will proxy requests to /svn to a private subversion server, requests to /files to a private fileserver, and return 404 for any other paths:def mapper(req): svn = SVNRelocator("http://www.example.com/svn","http://svn.example.com/") if svn.matchesLocal(req.reqURI): return svn.mapping # contains the (host,port,rewriter) tuple if req.reqURI.startswith("/files/"): return ("files.example.com",80,None) return None Requirements: · Python
