IE8 back button and dynamic content

Question

I have a page that pulls an external JavaScript file, which then generates some content dynamically into that page (basically inserts some DIVs and a Flash object).

When ever the user navigates away from this page and then pushes the 'back' button, Safari and Firefox display the generated content, but IE 8 does not.

What is the best practice for IE to retain dynamic content in history? Or do I have to listen for some specific event and then restart my JavaScript?

BTW, I have jQuery in place, so relevant plugin suggestions are also welcome.

If you click the Google link at the bottom and then go Back, Safari and FF will show you the video again, IE8 does not.

Answer 1

You should look into using a history plugin to get consistent results with dynamic content.

Here is a thread with some plugins jquery history plugin

Answer 2

I did a quick test using the IE Developer toolbar- I clicked back and nothing happened as you mentioned. I then tried again but before clicking back I cleared my cache, and when I went back the video showed up.

Try ensuring you force IE to clear the browser cache and your video should load even when clicking on the back page.

---- EDIT ADDED AFTER CACHING CONVERSATION ---

This should not affect the performance of your web application the client browser gains from caching, since you would send back headers to expire/disable the cache only for the page that fires off the JS to embed the video. Everything else- the JS scripts, the graphic/images, and event the video- would still be cached by the client.

---- EDIT: UPDATED TO INCLUDE FULL SOLUTION FROM COMMENTS ---

To disable caching of included JavaScript files one solution is to just append random number in query parameter to the URL, so that browser will not cache the result.

<script src="jquery.js?t=<?PHP echo rand() ?>">

This avoids the need to modify webserver settings to disable caching static JavaScript files system-wide.
