How to view Internet Explorer auto-detected proxy settings?

When Internet Explorer is set to auto-detect proxy settings, is there a way to view what it detects?

The settings are retrieved from http://wpad/wpad.dat which is a javascript file describing which proxy server should be used in which situation. Your best bet is to open that URL and figure the proxy out from the contents it returns.

"I tried both solutions mentioned, and also all sorts of others.

In the end what worked for me was using Chrome to navigate to:

chrome://net-internals/#proxy

which gave me the .pac file (= proxy auto-config file) which I could then download and read to determine the proxy that was being selected.

As pointed out by @DaveInCaz and @ZachBloomquist, this no longer works as of Chrome 71.

So what I did was:

Find the previous version of Chrome, which gives 70.0.3538.
Look this up on omahaproxy.appspot.com, which gives version 587811.
Find that version of Chromium on the snapshots page. The version seemed to be present on the Windows 64 bit version page, which leads me to the 587811 version page with the file chrome-win32.zip.
Download, unzip, run chrome.exe and you can again use the address chrome://net-internals/#proxy to find the PAC script!

So to summarize the steps required:

Download Chromium version 70.0.3538 = build 587811 here (Windows, otherwise see above steps).
Unzip and run chrome.exe
Navigate to chrome://net-internals/#proxy"
