global.asax has not that propose, the only events on that file are
Application and Server related, you can only log the user entry on your
website on that page
for what you want, you can always use the Master.Page
create a blank master.page with only the content control,
for all your webpages, say this is their master.page
on this masterpage use the Page_Load event to call a function that will
record the user id and webpage that is visiting (using
server.requestvariables() )
Another alternative from Bruno's suggestion is to create a base page
for which all of your other pages inherit from. Then implement the
audit logging in the base page.
