I'm assuming you mean you want to "push" data out to
the user's browser once every 5 minutes? That's hard,
because generally how it works is that the browser is
the one that requests data from the server.
Try checking the archives using keywords like "browser
push" and "equiv refresh" for some hints.
You'll find (discussed in much greater detail in the
archives and in books and at various web sites you can
easily find using google) that you can either:
a) Ask the browser to reload periodically from a
particular URL. In this case, you'd tell the
browser to reload once every 5 minutes. Not
all browsers allow this, though.
b) Write an applet that sets up a connection to
your server and waits for 'pushed' data. Applets
can be hard to deploy, though.
But, like I said, check the archives for more details
and more ideas.
General note: If you don't know the answer, or don't
understand the question, it's better to say nothing or
state very clearly that you're guessing. Personally,
I'd be careful about all the answers in this thread.
