/**
 * We are a conditionally-compliant HTTP/1.1 client with a cache. However, a lot of the rules for
 * proxies apply to us, as far as proper operation of the requests that pass through us. Generally
 * speaking, we want to make sure that any response returned from our HttpClient.execute() methods
 * is conditionally compliant with the rules for an HTTP/1.1 server, and that any requests we pass
 * downstream to the backend HttpClient are are conditionally compliant with the rules for an
 * HTTP/1.1 client.
 * <p/>
 * There are some cases where strictly behaving as a compliant caching proxy would result in strange
 * behavior, since we're attached as part of a client and are expected to be a drop-in replacement.
 * The test cases captured here document the places where we differ from the HTTP RFC.
