Hello all,
I have a question concerning Keep-Alives. I'm writing a SSL proxy
(which is working great except for this issue) and every time I got to
attach a file in an email the connection resets, and it gets caught in an
infinite retransmit loop. I've tested it with Gmail, and also with the
outlook here at the office. I can attach a small file (17KB tested) but
when I venture to a larger file (say 469KB for the image I'm testing) the
connection will never complete, and will continue to reset the transmission,
and loop. This behavior is only implemented in Firefox. In the other
browsers it seems to fail out with some error about unexpected reset. Is
there some parameter that I can set when establishing the SSL connection
that will allow me to wait for larger transfers without reseting?
Here is a sample of what I mean, this is the SSL_write() method output
(caution: long):

And then the process repeats nearly word for word.
However when I attach a smaller image it works perfectly and instead of
repeating a get a server HTTP/1.1 200 OK message.
Any information would be appreciated. Thank you.
