How can I track an asp.net pages size without tracing?

Question

I want to be able to track the amount of data that is being transfered from my web site to each user that accesses the site. I can do this for file downloads and such but what about the pure html content itself.

How can I track the output size of a page (or the data that's trasnfered via an AJAX call) to the client and log it against a particular users session?

Also how would this differ when GZip is used in IIS 6.0?

Answer 1

You could develop a HttpModule to do this as in this question. If you used a HttpModule to do this I would imagine compression is applied after this in IIS 6.0.

Answer 2

One more way without writing any special code

You just get this parameter

Response.Filter.Length
