Is it possible to have a dynamic content value in Meta Refresh Tag

[suresh dasari]

Hi,

In my JSF project I am using Meta Refresh Tag that refresh the current page every lets say 90 min.
so 90 min is the timeout session set in the application server. so even though the page is active it is refreshing every 90 mins that shouldnt be the case.
to do so I need to get the content value dynamically, so the below code

<meta http-equiv="refresh" content="600;url=http://www.google.com">

form the above code content value is 10 minutes (600 seconds), so page will refresh every 10 minutes, if I get this value dynamically from the websphere then if the page is idle for 10 minutes then only page will refresh if not the content value will always get updated until the user uses the page.
so my question is Is it possible to have a dynamic content value in Meta Refresh Tag?
