I have a asp page with some custom list controls, where a user can select thousand of selections for each list control.
Ex: Page contains,
User field (1,00,000 user can be selected),
Items field (80000 items can be selected),
Names field (1,20, 000 names can be selected).
During save, if page length is less then 4MB then the saving process completes succesfully, else it throughs "operation not allowed" error.
