1556996 - Manual proxy configuration doesn't send traffic from/to localhost through the proxy

Status: RESOLVED DUPLICATE of bug 1535581

(Core :: Networking, defect)

Description

[Miro]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/74.0.3729.169 Safari/537.36

Steps to reproduce:

I configured the proxy using the Manual proxy configuration. Settings:

• HTTP proxy: 127.0.0.1
• Port: 5555
• "Use this proxy server for all protocols" is checked.
• No proxy for box only contains: .google.com
  OS: ubuntu 18.04.2 LTS
  I have apache2 running locally and serving a web page.

Actual results:

All the traffic, except traffic to 127.0.0.1, localhost, and .google.com, is going through my proxy.

Expected results:

Since no proxy -box doesn't contain the "localhost", traffic to/from the localhost should also go through my proxy.
