caching only sections of a webpage

[yeehawjared]

I'm building a website that serves dynamic content.  I followed this guide to cache each page:

The only problem is that I have a user login at the top of every page, and I'd like to keep it this way.

 

http://www.guitarvideotabs.com/home.php  - example of the page in question.  I'd like to cache only the main content.. basically everything but the div "logintop"

 

Any links to php caching tutorials / howto's would be greatly appreciated, I'm a noob with php caching.  Thanks guys.

seems like this could help me:  caching with smarty

Seems like that'd work... only problem is that I don't have root access to the box.  I'm using dreamhost to host my site.  I downloaded and extracted it.  Seems to be working.  Now to get my pages cached.

 

If anyone knows of any better ways to selectively cache php/mysql sites please post.  Thanks
