>>In general, there is no way to modify HTTP such that an invisible >>broken proxy can be detected. > >Is this really true? It seems a very sweeping statement. It is true provided that the proxy remains invisible. Note, however, that HTTP/1.1 requires that a proxy be visible. We have done all that we can do from an application protocol standpoint. Note also that I distinguish between a proxy and a tunnel in the spec. The problem with Gauntlet is that it is either a broken proxy or a really lousy tunnel, and thus it is not interoperable with other HTTP applications. In this case, Gauntlet is only visible when a chunked encoding is used to delimit the message length, at which time it screws it up. MSIE wants to detect it *before* it becomes visible, which is difficult. .....Roy
