I want to access the 'script' tags in the HTML HEAD section of my page from the server but adding the instruction runat="server" to them seems to cause all sorts of strange behaviour. For example, simply adding runat="server" to a single script tag on the login page for one of my apps gives the...

I have an iframe which, in certain circumstances, needs to nullify the onbeforeunload event of its parent window. I thought I could just use window.parent.onbeforeunload = null; but this doesn't seem to work. Can anyone help? Before anyone gets huffy about the use of frames and IE-only events, I...

I was using Windows authentication in a ASP.NET 1.1 intranet app I'm writing. Now trying to change to FormsAuthentication which I believe I've set up correctly.
