Google Ends Internet Explorer 9 Support In Google Apps
An anonymous reader writes "Google has announced it is discontinuing support for Internet Explorer 9 in Google Apps, including its Business, Education, and Government editions. Google says it has stopped all testing and engineering work related to IE9, given that IE11 was released on October 17 along with Windows 8.1. This means that IE9 users who access Gmail and other Google Apps services will be notified 'within the next few weeks' that they need to upgrade to a more modern browser. Google says this will either happen through an in-product notification message or an interstitial page."
You listed IE-specific solutions, then complain that only IE supports them.
Want reliable proxy autodetect? Most other browsers break on DHCP based WPAD.
Use a transparent proxy. Those stupid proxy servers that you have to configure in each application suck. Most applications don't support it. Secure download sites don't work, secure FTP is unreliable. Even Microsoft's own MSDN download manager doesn't support a proxy server.
Want to deploy links, manage security zones, etc via group policy?
By "deploy links" I take that to mean "shove bookmarks into people's browsers" which is better handled by putting those links on the intranet site. That works with any browser, any OS, with less work. No special corporate policy required.
The primary purpose of security zones is so you can run ActiveX controls. No other browser needs special security settings for ActiveX.
