I had a report that the Windows free-as-in-beer proxy tool 'FreeProxy' didn't work with the new HTTP proxy code, and it turns out that the first reason why not is that the error-document in its 407 response is sent via chunked transfer encoding, which is to say, instead of an up-front Content-length header, you receive a sequence of chunks each prefixed with a hex length. (In 0.76, before the rewritten proxy support, we never even noticed this because we sent Basic auth details up front in our first attempt, rather than attempting a no-auth connection first and waiting to see what kind of auth the proxy asks us for. So we'd only ever see a 407 if the auth details were refused - and since 0.76 didn't have interactive proxy auth prompts, there was nothing we could do at that point but abort immediately, without attempting to parse the rest of the 407 at all.) Now we spot the Transfer-encoding header and successfully parse chunked transfers. Happily, we don't need to worry about the further transfer-encodings such as 'gzip', because we're not actually _using_ the error document - we only have to skip over it to find the end of the HTTP response. This still doesn't make PuTTY work with FreeProxy, because there are further problems hiding behind that one, which I'll fix in following commits. |
