Change Cache-Control: no-cache to no-store?

[Matej Knopp]

Hi,

we have a serious problem with ajax and back button. To see it in 
action, go to the tree example, expand a tree node, go to a different 
page, press back button and you'll see the node collapsed. However 
trying to expand it, you'll see bunch of errors.

Why?

The problem is that cached page reflects the page when it was first time 
retrieved from the server. However, doing Ajax updates, the page could 
have been significantly changed. So if you go using back button to go to 
page with ajax components, there's a big chance that it's out of sync 
with server.

Currently I can't think of any way around this, except to force reload 
the page on back button, using Cache-Control: no-store.

I know many of you are probably against reloading page on back button, 
but what else can we do?
