Yes, I have write some C TCP/UDP web clients and servers in the past and I don't have an issue there. What I have is an embedded system, that needs to process the test output from a cgi file. I hust need a little info on the way to decode this data. I send a post command to the cgi file on the server and wait for a response. Instead of the desired test response, which should be "Hello", I receive the text responses "Download" and "OK".
I will read up on cURL to find out the details on the ports so I can decode the text.
