Modify POST from HTTP to HTTPS on the same VS

Hello,

I have one application published over port 5100 (and cannot be changed) and whenever i configured a VS wihtout client ssl profile the whole application works. Although when i associate a proper client SSL profile without server SSL (the application is plain http) it works almost everything except authentication. I've discovered that whenever i send my credentials these are sent over POST that is pointing to the appropriate ip and port but on https. Since the F5 is expecting https it will automatically discard the POTS.

Is there any way to either modify the POST that the user will sent to https or create any allowance on the VS for an specific POST on plain HTTP?. The port remains the same, so i cannot redirect the packet to any non HTTPS VS on different port.

Thank you
