Ajax & the Back button III. To boldly go where they have just come from.

It starts with a simple question.
A question that didn’t seem relevant until a bunch of others had been decided. A question that too often catches us by surprise.
The client asks - “So what happens if I click the back button?”
Why would they ask? There are many reasons, but the primary is that it is a convention they already know. The back button is one of the most reliable & flexible controls in a browser. People hit the back button when:
_ They didn’t go where they meant too.
_ They didn’t find what they were looking for
_ The server is slow and the page isn’t loading
_ The network is slow and the page isn’t loading
_ Someone designed a huge flash file into the page & failed to warn the user, so they think the site is broken
_ Someone designed poorly tested javascript or other code into the page & it is crashing the browser
User are drawn to the back button like moths to a flame. We see this often in mirrored testing, it precipitates a greek chorus of UXD people behind the glass moaning and wringing thier hands.
