Continous Swf Movie

Lets say I have a flash banner on my website.

Its on several pages but its the same exact swf.

What can I do to make the swf movie continous all throught the site.

For Example

If you go on the homepage and see the banner then you go to another page it restarts from the beginning. Instead I just want it to keep going from where it left off whenever the user goes to a different page.

Thanks
