Hi all, I have an asp.net 1.1 web app that uses mobile controls and forms
authentication. I recently added a "remember me" functionality, allowing the
user to stay logged into the site between browser sessions (the login page
makes use of the RedirectFromLoginPage method).

In doing so, I am getting an intermittent error:

"The page requires session state that is no longer available. Either the
session has expired, the client did not send a valid session cookie, or the
session state history size is too small. Try increasing the history size or
session expiry limit."

This happens when a user tries to re-submit a form that has data driven drop
down boxes. The weird thing is, the form works on the first pass; but, if
the user drills down into the site, then uses the "Back" button to get back
to the form, they get the error. They can bypass it by clicking the link to
bring up the form, which then re-populates all the drop down boxes.

I have a sense that this is something simple, but have no idea what it might
be. Any help is appreciated, thanks.

I'm sorry if this post precludes any valid responses, however I've had
similar issues with either using javascript Back()-1, or the browser back
button...

So I script my own back buttons that I run into an overloaded method for any
similar controls.

I use this by setting the commandArg and Text as needed on any previous
post, I keep them in Nav panels.

Anyway it functions for the current datagrid (I know... badthing) to step
back thru the recordset or to actually go back to a previous page.

I get most if not all of what I need to know from the cmdArg.

Painful as it is to do, it enables me to have more control and less suspects
as to why it's not working.

HTH
