If you enable -DLWS_WITH_HTTP_PROXY=1 at cmake, the test server has a new URI path http://localhost:7681/proxytest If you visit here, a client connection to http://example.com:80 is spawned, and the results piped on to your original connection. Also with LWS_WITH_HTTP_PROXY enabled at cmake, lws wants to link to an additional library, "libhubbub". This allows lws to do html rewriting on the fly, adjusting proxied urls in a lightweight and fast way.
