Maxim Dounin,
Thanks for your prompt reply~ ^ ^
Actually In my script, the tcp stream is encrypted and disguised as a normal chunked downloaded file to pass the firewall, and I need to control every chunk(the stream is encrypted in blocks, and a chunk represents a block) so that there is no specific protocol identification.
If the script cannot control the process of chunked encoding, it should have some identification so that the firewall can update itself to find out the proxy stream.
There are many web hostings that use nginx + php-fpm, so I wrote the script in PHP.
Does that mean I cannot use nginx as a web server in this way?
Nginx is an excellent web server with good proformance, I'm not willing to give up this server.
Thanks.
