jstl

I use javascript and css to build a multi-level drop down menu with following markups:

<ul>
   <li>menu item 1</li>
       <ul>
         <li><a href="#">sub menu menu item 1</a></li>
         .................

This markup is generated by a custom JSTL tag <mui:menu .../> which loads menu data from a database.

I hope my jsp page can behave like this:

if menu data has not changed since last time I visited the page, just use browser's cache
otherwise load from database...

How can I do it? I don't know much detail about cache mechanism.
