# = Testing Proxy Settings
#
# These tests check the proper proxy server settings by running two
# web servers.  The web server at http://localhost:#{SERVER_PORT}
# represents the normal gem server and returns a gemspec with a rake
# version of 0.4.11.  The web server at http://localhost:#{PROXY_PORT}
# represents the proxy server and returns a different dataset where
# rake has version 0.4.2.  This allows us to detect which server is
# returning the data.
#
# Note that the proxy server is not a *real* proxy server.  But our
# software doesn't really care, as long as we hit the proxy URL when a
# proxy is configured.
