24 /* Overview:
25 *
26 * We have an echo server, two proxy servers, two GProxy
27 * implementations, and two GProxyResolver implementations.
28 *
29 * The echo server runs at @server.server_addr (on
30 * @server.server_port).
31 *
32 * The two proxy servers, A and B, run on @proxy_a.port and
33 * @proxy_b.port, with @proxy_a.uri and @proxy_b.uri pointing to them.
34 * The "negotiation" with the two proxies is just sending the single
35 * letter "a" or "b" and receiving it back in uppercase; the proxy
36 * then connects to @server_addr.
37 *
38 * Proxy A supports "alpha://" URIs, and does not support hostname
39 * resolution, and Proxy B supports "beta://" URIs, and does support
40 * hostname resolution (but it just ignores the hostname and always
41 * connects to @server_addr anyway).
42 *
43 * The default GProxyResolver (GTestProxyResolver) looks at its URI
44 * and returns [ "direct://" ] for "simple://" URIs, and [
45 * proxy_a.uri, proxy_b.uri ] for other URIs. The other GProxyResolver
46 * (GTestAltProxyResolver) always returns [ proxy_a.uri ].
