Creating a universal error page

[shaqtus]

I was wondering whether I could somehow create a universal error page for my website. For instance, if a user tries to navigate manually to a certain page of the website that requires you to be logged in, that user gets redirected to an error page that says something like, "You must be logged in to view this page." Similarly, there will be other error pages for certain functions of the website. My question is: Is there any way that I can create one single ASP .NET Web Form page where the text on the page changes dynamically? Currently, I have a separate Web Form for every type of error, and that seems a bit inefficient to me.
