Hi
Actually I have created a toolbar for IE which will be changed after
user loggs into our site and will be changed again after he logs
out.These things I have done ,but the problem comes when it is session
expiry.if the user does not do anything for 20 minutes in our
site,then the session will expire and according to that the toolbar
should also be changed again.How can I achieve that?My idea was to get
the cookie value for that user when he logs in and firing a MySql
query with the cookie value to our database each time when there is a
page navigation or page refresh.If my query returns with no value,then
it will mean that session has expired and according to that I will
change the toolbar.I am retrieving the cookie value.But there are some
problems:
1.I need to fire the query in DownloadBegin or DownloadComplete,but
this is making IE very slow and IE is crashing.Moreover what I have
dicovered is that,in IE6 if I dont do a page refresh or site
navigation,simply if i just move the mouse over the page,then also the
flow is coming to downloadbegin too many times,means that many times
the query will be fired......oooops..that will be dangerous.where
should I fire the query then?

I would have the concept of registering for notifications from the server
over a separate port, so when the server logs out the user, it notifies your
toolbar over the port. This business about the toolbar monitoring every
DownloadBegin and so forth simply isn't cutting it.
