Displaying an in-progress page while navigating from one page to another

["Prasad, Kamakshya" <kp...@capitalservicing.co.jp>]

Hi All,
 
In our system we have some pages which take lot of time to process
because of the complicated back end logic. So, sometimes the navigation
from one page to another page is very slow. 
What our client wants is to show an intermediate revolving gif with some
informative text in it before the next page loads.
 
What I heard that it's possible to put some links in header of HTML
which can show an intermediate page before the next page loads. Could
anyone let me know about HTML head option?
 
We are using struts framework for our web tier. So I want to know if
there are any options in struts to do so.
