redirect - PHP Show other page while uploading a file -

i wondering if it's possible show different page while uploading large file.

<form enctype="multipart/form-data" method="post" action="user.php?inh=user/uploading"> 

when click on "submit" send out form , upload file, starts uploading on same page without notification. want redirect users page can see loading gif , bit more information stuff filled in, in rest of form.

anyone ideas how can show visitors "user.php?inh=user/uploading" instead of waiting finish upload , redirect me page.

imo, best plan of attack use ajax handle upload.
