Autoit script to use a remote pc as proxy.We are compiling this script as gproxy.exe.
Then we upload gproxy.exe,plink.exe (ssh client) and config.ini to remote host.After running gproxy exe
(locally running bitwise ssh server)

plink.exe -R 8080:127.0.0.1:8080 -R 8081:127.0.0.1:8081 myip -l test -pw 123456

it connects to our ssh server with this command.It works on port 8080 for normal proxy but
ssl proxy on port 8081 doesnt work.
any idea?


config.ini:



[SYSTEM]
PROXYPORT=8080
PROXYIP=127.0.0.1
PROXYPORTSSL=8081
