in reply to LWP 500 Internal response read timeout

interesting .. that 500 error message 'read timeoutt' is a rather odd spelling and I expect it's not coming from LWP but from the target server. Sorry I cannot think of a reason off the top of my head, but here's how I would approach the problem:

  • double check the PHP client to ensure you're sending all the info (any missing headers?)
  • if you have access to the target server, check its' logs for clues
  • use a command line client (like curl) to see if you get success or the same error
  • make use of LWP::UserAgent's handlers to better inspect the data. Look at the response_data and response_done handlers -- the wireshark output leads me to believe that some of the data is coming down the pipe (chunked response?) but then the target server throws a 500 so LWP::UserAgent drops the chunks already received (and that my fellow monks is a wild guess!)

    I modified LWP code to print out "timeoutt" just ensure it's coming from LWP. And yes the "transfer-encoding" is "chunked". Again, the timeout message is not from target server.

      There were some issues with certain version of Net::HTTP and chunked responses.

        OK, so do you have any workaround or link or something to resolve this?
        I updated LWP::UserAgent, Net::HTTP to the latest:
        perl -MNet::HTTP -e 'print "$Net::HTTP::VERSION\n"' 6.06

        The timeout issue is still there.
