saving cache upon destory to use with new tab set

saving cache upon destory to use with new tab set


i and using one tab template to load mutiple tab groups.
the tabs are loading data via ajax and each tab group's tabs have
unique urls
so when a new tab group is selected i destroy the current one and
change the url's them build a new tab group.
this works fine.
What i would like to do is keep the cache from tabgroup to tabgroup
and just build upon it so that when a user goes from tabgroup a to
tabgroup b then back to tabgroup a, the content is still cached.
