Is there any way to determine the amount of time a client spends on a web page

Question

Assuming I have an open source web server or proxy I can enhance, let's say apache or squid.

Is there a way to determine the time each client spends on a web page?

HTTP is of course stateless, so it's not trivial, but maybe someone has an idea on how to approach this problem?

Answer 1

With Apache or Squid you hardly can detect the time a user spends on your page.

But with some additional sugar on your webpage you can:

• Try Google Analytics.

It's free and has a lot of functions.

But you'll also invite Google to watch the stats of your site ... (but maybe that helps them to decide if you wanna buy you :-))
