I implement multiple upload with only iframe. Each upload occur only  
the previous upload is finished or no current upload is taken place.  
Each file upload has its own form. All form has “target” attribute  
reference to an iframe in my page. It was successful, but there is a  
big problem with the browser history. When I click back browser  
button, it will upload the last file that I already uploaded. Do all  
of you have a trick related to how to manage browser history or is  
there any ways to upload with iframe without adding to browser’s  
history? Or do you guys have any ideas? Always appreciate with your  
idea.

Thanks
