Ajax Application that saves state ...

[hc69]

Hey guys,

I am new here and have a question ...

I am trying to create an Ajax Application that saves the last state ... now I know the Ajax "back button" problem is well known, but what I am looking to do is not create a history of all the states just the last state.

an example of this being done is believe it or not at ebaumsworld ... EBAUMSWORLD - Funny Pictures, Hilarious Videos, Flash Games and Jokes

clicking on the above link will take you to the site, now click on one of the page numbers for the video, say "5", the ajax then loads videos from page "5", now go to a different page, either click on a video or go to your homepage, then hit back and the page is still at "5" hit back again and you are back to your orginal page before ebaumsworld...

how can I do this? i have everything working but if i click on the "5" page leave my application and go back, it is at page "1" instead of "5"...

thanks in advance for you help...

Depending on the complexity of your application you have a number of choices

• Store the State of the Application in hidden forms
• Store the State in a Database
• Store the State in the URL
• Store the State in a Server Side Continuation

Most of those are differnt ways of saying the same thing though. Basically the web server has to have some way to relate the user's GET or POST request to some stored data on the server to allow it to "remember" where the user left off.

If you were going to use a database, you might store an identifier for the session in a cookie, then use that identifier as a key in a database row where you store the other variables your application needs to track.

Of course eventually you have to get rid of all those stored sessions in your database. You can't always depend on users to log out but your application shouldn't just wipe a user's session while they're browsing!
