I have an unusual problem. Every page in my web application is loading twice! When debugging the onload event is hit twice. I have checked iis logs and have seen same.
My application is .net 3.5, asp.net c# running in IIS7.
It is occurring in multiple different environments.
It is not just one page but all pages on the site. To test this I created a blank page, with no markup eg. not empty source tags on images or iframe which I read may cause it. I also removed all httpmodules from web.config and httphandlers but its still occuring.
I am out of ideas now so anyone have any advice or tips for me?
There can be different reasons,
