How to intercept a page request prior to the actual page load

P: 5
When a page is requested in the .net architecture I believe there are a number of events that happen prior to .net actually trying to find the page in the file system.

I would like to intercept the page request at that point to interrogate the requested page for possible redirect.

I remember that in ASP 1.0 this was possible.

Does anyone have an idea how to do this in Dot Net?

The issue is that I would like to create a virtual file system. I have a number of files stored in a SQL DB. For example picture.jpg.

the way to access this is to create an ASPX file that when called is passed a parameter the contains the file to display and then return the data so that the browser can display the image. i.e. http://www.mywebsite.com/displayimage.aspx?ID=picutre.jpg

This certainly works but it would be nice to be able to use http://www.mywebsite.com/picture.jpg When picture.jpg exists in a SQL server DB. To do this I would need to intercept the request string and see if the request is for a jpg image. Then search the DB for that image. If it exists return the image as if it was being returned from the file system.

Any ideas?
