IE ASP Error Handling
I am getting those nasty error500 pages when my ASP code isn't correct and can't see any information on the error that it produces ?
Go to Extra>Internet Options, click the Advanced Tab and go to the category Surfing and uncheck the line that says:
show userfriendly HTTP error messages (or something simular)
This way you will get some information on the error of your ASP page.
