double submission of forms

[Nanduri, Amarnath]

Hi all,
 
        Will struts be able to handle the double posting of forms ? 
For example if a user submits a form, and when the processing is taking
place on the server, he submits information again (or uses the back button
of browser to submit information). Will struts be able to ignore the second
posting of form ? Thanks  alot.

cheers,
Amar..
