I have a request to the server that could take upto 10 mins to come back
and display the results.
I want to either
a) Redirect to a new "Please wait" page till the processing is done, then
redirect back to the results page , or
b) Display a "Please wait" message on the same page that sends the request
to the server and refresh the page to display the results.
I know websites like orbitz and travelocity do this.

Any idea how I would accomplish this?

Thanks,
-SJ.
