[thelist] Redirect AFTER Page loaded with ASP

[Ken Schaefer]

Because...

a) User posts form
b) ASP code runs, handling the upload
c) ASP code emits HTML to generate "uploading" graphic
d) HTML code has to be flushed from buffer to client (so client can render 
the "uploading" graphic)
e) More ASP code needs to run in the background, continuing to handling 
upload, whilst continuously sending updates about progress, somehow, to 
client
f) Server.Execute needs to happen to another ASP page, which then emits some 
client-side code to replace the current emitted HTML that's already being 
displayed on the user's screen, with the appropriate status message (upload 
succeeded or failed)

Now, given that client-side code has to be emitted, what's the benefit of 
Server.Execute? Why not have the current page emit the client-side script?

Secondly, how is (e) accomplished? You somehow have an ASP page running on 
the server communicating to and updating a page already rendered on the 
client, without any interaction from the user (Java Applets, ActiveX, other 
browser plugins excepted)

Cheers
Ken
