Proxy example

Via the wsf_proxy library, it is possible to implement a simple reverse proxy service.

This example forwards request based on server name, or location as described below:

• if server name is foo, forwards to http://localhost:8080/foo
• if server name is bar, forwards to http://localhost:8080/bar
• if path starts with "/search/", forwards to http://www.google.com/search?q=

For instance:

• http://foo/a/test -> http://localhost:8080/foo/a/test
• http://localhost:9090/search/eiffel -> http://www.google.com/search?q=eiffel

Notes:

• look at {APPLICATION_EXECUTION}.execute for the implementation.
• the send_proxy_response implements a general forwarding, but for more advanced need, this could be customized per forwarding. For instance, a specific forwarding, may need the X-Forwarded headers, or to keep the Host from the client, ...
