flash header and AJAX

Hi everybody,

I have a question. I busy to make a site:) And i want to put in some ajax futers.

My site has the follow structur

Header div
( this is the menu of the site in flash, it will be include with the php include function)

Content div
( this is the div with al the content)

footer div
( the div for the footer)

Now my question is:
Can i use AjAX on this site so when i press on the flash button he wil load the page i wish into the content div?

How does this work?

I hope someone can help me!
