We have an application where we'd like to prevent the user from navigating
within the application using bookmarks or their history. If they do this, in
most cases, the proper queries will not have run and the application will be in
an indeterminate state.
We thought the solution was to simply look at the http "referer" header and if
that value was null, it meant that they did not click a hyperlink within our
application when they hit the page. Unfortunately, we have situations where
this is null. (I really don't know why this would be true, but it is.)
So, what's the solution for something like this? We know the user is logged
in, as that's another check, we just want to make sure they perform legal
operations, such as:
form b
you can get here via :
form a only
form c
you can get here via:
form (b) next
form (d) previous
form (c) postback
Thanks for any suggestions.
