I have a browser (FF) using proxy, with use this proxy server for all protocols option enabled. How will DNS behave? Will it go through proxy as well?

Background:

I want to monitor and modify my network traffic, using this simple proxy written with twisted as an example

"use this proxy server for all protocols " probably means all protocols used in the URL

i.e.

It does not mean every protocol that might be used by the OS in servicing this request

  • ARP
  • ICMP
  • DNS
  • SMB

Make sure that your local DNS settings can resolve your proxy server domain,then it will go through the remote proxy server as well.When I use firefox,local dns server can resolve a proxy server domain,but with GFW DNS pollution,I cannot browser twitter.But I can open twitter website when the proxy is on.
