[Tip] Intercept localhost web packet with Burp

I needed to test the local web application. As usual, I was going to use Burpsuite but localhost traffic didn’t intercepted. So I googled about this. It was take little much time to find out than i thought. (Firefox blah blah… I’m not big fan of it. I’m using Chrome + SwitchyOmega(chrome extension))

Anyway, If you need to capture local traffic, Add a new entry in /etc/hosts file with a new hostname pointing to 127.0.0.1. I added lokalhost for hostname. Like this:

##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting.  Do not change this entry.
##
127.0.0.1   localhost
127.0.0.1   lokalhost

...

If the settings for the proxy have been set up properly, intercepting will work.
