Windows 10: IE and Edge ignore PAC (proxy auto config) file

IE and Edge are ignoring PAC script file. The file is on a webserver using HTTPS. If changing the URL to HTTP it works fine. Is there any known issue with Windows? I started seeing this behavior with Windows 10 Build 1903 but I'm not sure if it wasn't present on previous builds.


Again, using https://someserver/script.pac does NOT work. Using http://someserver/script.pac works.


Note: This could potentially be an issue with WinHTTP, as other browsers work perfectly, like Firefox or Chrome. I'm not sure but I think they use WinINet.

Proxy auto-config file on server works in Chrome but doesn`t work in IE11

Hi, thanks for the reply!

Currently Microsoft Edge don`t work as well, only Chrome can recognize my library proxy.

Also I have tried library proxy for another university, and it is a "proxy.pac" file rather than my university`s "proxy.pac.js" file. This time IE11, Microsoft Edge and Chrome all work perfectly. It seems true that Chrome can accept both .js and .pac file,
but IE11 and Edge only accept .pac file.

 

Proxy auto-config file on server works in Chrome but doesn`t work in IE11

Hi all,

I am trying to access the academic resources provided by my university`s library using IE11 on my windows 10 machine (Build 10586). The library offers a auto-config script on the server and tells us to use "automatic configuration script" in "LAN Settings"
of Internet Options. However after I enter the network address for the script, IE connect to the internet just like direct connection, the university`s login page does not show up when I load websites like ScienceDirect, Springerlink, etc.

I also have Chrome installed, and it is using my computer's system proxy settings to connect to the network (so IE11 and Chrome share the same proxy settings here). And Chrome works perfectly. When I load academic websites my university`s login page shows
and after login I can download articles with no problem.

Therefore I think I have config the settings correctly, and IE itself might have a problem.

Also I have look into the internet address of the auto-config script, and find it`s name is a little bit strange. The file name is "proxy.pac.js" rather than "proxy.pac". Is it possible that Chrome accepts both .pac and .js file but IE11 only accepts .pac
file?

Tkanks.
