Hi,

I'm capturing with a PAC file configured which chains to an upstream proxy (or goes direct for hosts on the local network).  Is there a method of identifying whether a session in fiddler was proxied or sent direct?

Thanks,

Gaz.

Hello Gareth,

You could use the x-hostIP session flag or the public string Session.m_hostIP member.

You could either add a custom column into the Fiddler's web session list, or modify the FiddlerScript as it best fits your needs.

Hi Simeon,

I'm troubleshooting an issue where I'd like to ascertain if the browser is reading into a PAC file correctly and sending traffic as per the condition set either to either 'go direct' or via an upstream proxy. 

I've just started using Fiddler Everywhere hence would appreciate if u could provide details as to how I could achieve that.

Many thanks,

Gee Jay

Hello Gee Jay,

 

Fiddler Еverywhere does not (yet) provide the option to add custom columns. But what Simeon suggested is to use the x-hostIp flag, which is already implemented in Fiddler Everywhere as the Remote IP column. You could add your Remote IP column explicitly by clicking the three vertical dots next to any column (in the Live Traffic list), expanding the Columns section, and finally checking the Remote IP column. After that, all the logged traffic will also show the remote IP, identical to the x-hostIp flag in the classic Fiddler.
