fteproxy server's response to malformed messages

Raised here: https://trac.torproject.org/projects/tor/ticket/12673

cypherpunks suggests that fteproxy, when using an HTTP regex, should tolerate a range of HTTP headers. Specifically, an fteproxy server when using HTTP will terminate the connection, if the following is submitted:

GET /<encoded_data> HTTP/1.1\r\n
Host: tpo.org\r\n
User-Agent: Mozilla/5.0 (Windows NT 6.1; rv:24.0) Gecko/20100101 Firefox/24.0\r\n
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8\r\n
Accept-Language: en-us,en;q=0.5\r\n
Accept-Encoding: gzip, deflate\r\n
Connection: keep-alive\r\n
\r\n

It turns out that this is a complex issue to solve in general, as one solution we could allow custom error handlers in fteproxy that are activated under certain cases.

As a step towards this, we should probably distinguish between the following two cases:

  • The server receives a message that is in the language specified by the regex, but is malformed.
  • The server receives a message that is NOT in the language specified by the regex, and is, by definition, malformed.

Thoughts?
