Hi There,

I am working through an issue with a script that builds a socket connection to stunnel. Stunnel is being used to relay to an Apache web server. I'm building a localhost TCP connection on port 54322, and writing my HTTP data. When reading data back from the socket connection in my script I'm sometimes getting nothing, and other times getting the proper result. I can confirm that the web server is always receiving the request and returning a proper response. Wireshark shows SSL data being transmitted and received, so stunnel is doing its thing. However, the response does not seem to be relayed to my script on the other side of stunnel *sometimes*.

My hunch is that I am doing something wrong with my script, but I am hoping that an stunnel guru can rule out any oddities with my stunnel setup. My config is below as well as the output of my log file.

Any thoughts?

Thanks!

Mike
