HTTPS connections over proxy servers

Question

Is it possible to have HTTPS connections over proxy servers? If yes, what kind of proxy server allows this?

Duplicated with How to use Socks 5 proxy with Apache HTT

Answer 1

I had tried

• start tunneling: ssh -N -D 12345 login@proxy_server
• Setting the proxy in the firefox settings as localhost:12345
  • and ticking "use this proxy for all protocols"

but this resulted in the error "Insecure connection" whenever I tried to connect to an https website.

The solution was to

• "untick" the "use this proxy for all protocols"
• set the proxy "localhost:12345" only as a SOCKS proxy
• and leave the HTTP proxy, SSL proxy, FTP proxy blank
