Just update selected divs

[Tlg]

Hi!

Is there a way (ajax/jquery) to update just selected divs?

Check the image.

Div 1, 3 and 4 wont never need to update.

Div 2 and 6 are the ones who should update when click on a link.
When update, they will collect different pages depending on link using SSI.

Div 5 and 7 will have autoupdate.

I'm looking for something like facebook. If you click a link, top menu or chat won't reload.

Forgot! Div 2 is meant to be the "main" page. Div 6 will just update same SSI.

What do you mean 'selected' divs? A class?

I mean all divs are class="div1" class="div2" and so on.
If I have a menu in class="div3" then class="2" should update and collect data from another file.

Like this:
In div 3 there is a menu, and if I click "cars" then div 2 should get data from #include file="cars.asp"
At the same time, div 6 will refresh with #include="div6.asp"

If I click "bikes" (in menu in div 3) then div 2 should get data from #include file="bikes.asp"
At the same time, div 6 will refresh with #include="div6.asp"

Like a target to a div instead of iframe.
Isn't that something like facebook?

How has Facebook solved with just update center of their site?
If you chat with someone and click on a link, chatwindows will not update. Just the center of the page?
