Okay - I can see that just dislaying an 'upload in progress' would be the
best way to do this.
So I follow this path :-)

Which leaves me with one last question:
PageA contains the <form> that has a <input type="file"> element.
PageB contains a text saying 'Upload in progress ...'
When that form is submitted, the page won't return until the entire file
is uploaded (and then the wait text won't get displayed).
So what I need to do is to make some sort of hidden frame that submits the
form ?

How would you do this ? (sorry - it's not obvious for me)
