This would be a question for anyone who has code in the App_Code folder and uses a hardware load balancer. Its true the hardware load balancer could be set to sticky sessions to solve the issue, but in a perfect world, I would like the feature turned off.
When a file in the App_Code folder, and the site is not pre-compiled iis will generate random file names for these files.
server1 '/ajax/SomeControl, App_Code.tjazq3hb.ashx' server2 '/ajax/SomeControl, App_Code.wzp3akyu.ashx' So when a user posts the page and gets transfered to the other server nothing works.
Does anyone have a solution for this? I could change to a pre-compiled web-site, but we would lose the ability for our QA department to just promote the changed files.
You could move whatever is in your app_code to an external class library if your QA dept can promote that entire library. I think you are stuck with sticky sessions if you can’t find a convenient or tolerable way to switch to a pre-compiled site.
