Basically my when I upload it just does a standard html form upload
but my you'll see from my urls that that maps to upload.POST(). While
this is happening (as I send the form upload result to an iframe) I
send a progress.GET every 2 seconds from my javascript. Ignore the
references to 'code' - its just the old way I did sessions.
The problem seems to be that the gets take about 10 or 20 seconds to
return so the upload progress is so far behind it doesn't seem to do
anything for maybe 30 seconds.
Also, where I block the POST request you'll see I do a check for a
variable that I change in the progress.GET. I have a feeling this
doesn't work as the session.finished value isn't updated. Or is it?
Thanks again for all the help guys!
