I've got a .NET app that is working just fine on some machines, but failing to load on others. We're tried various browsers, O/S, networks, cleared caches, reboots, and still fail to load the page in some cases.
I've traced with Firebug as see that my homepage that is hanging, is getting stuck on some js files are only used in other pages in the application, NOT the homepage itself. I can't figure out why IIS is looking for these, unless it's caching somewhere, but we've bounced IIS a bunch already.
This application was just moved to a new AWS Windows server, that should have ample processing power. It was living on a Rackspace Win server 2008R2 / IIS 7 before and not having this issue, so I feel like it's something in the Win Server 2012 / IIS 8 settings or something.
