Safari 6.0 with proxy.pac

I just upgraded safari to version 6.0 and now my browser is experiencing issues attempting to access the internet when connected to the internet via VPN (Juniper). A proxy pac file is automatically pushed out by the gateway. This worked fine before upgrading to 6.0. Is anyone else experiencing the same issue? How did you resolve it?


I've tried manually entering the proxy information as well but that fails also.

Just add the following to the file com.apple.WebProcess.sb.

Please add it below the Basic system paths and above the FIXME: or System and user preferences:


;; Plugins

(subpath "/Library/Internet Plug-Ins")

(home-subpath "/Library/Internet Plug-Ins")


And it's fixed.


You can find the com.apple.WebProcess.sb here: /System/Library/StagedFrameworks/Safari/WebKit2.framework/WebProcess.app/Conten ts/Resources

This was helpful but the entries were already there and I'm still unable to browse the internet whilst connected to VPN. As others have also pointed out, other browsers except safari seem to work flawlessly so this is unique to Safari 6.

I think it depends upon the VPN software and if the company completely ignored Apple's guidelines.


For instance Juniper blew off Apple's guidelines and implemented their own proxy mechanism that is dynamically created as a plug-in when you're logged inot the VPN. Thus, svvemmy's solution worked for me.


Your experience has clearly varied.


The other browsers, and indeed most other software products using net access, use the Apple guidlines to communicate via proxy. So, they work through updates.


It just lousy VPN software. Juniper has screwed this up twice because they are so superior that they don't have to follow manufacturer programming guidelines. What a bunch of maroons!
