How to retrieve userid from html application

[Jean-Noel Colin]

Hi

I have a plain html application running under apache. I have protected
the directory where the application resides using CAS, but now, i would
like to be able to retrieve userid used to login from the html page. As
html is static, I guess I would need to have some server-side scripting
to retrieve that information? What's the easiest way?

Best regards
