[TYPO3-mvc] Cached plugin with partially uncached content

[Jan Kornblum]

Hi newgroup,

i've got a frontend plugin with a cached "showAction". This plugin / 
action should be extended to additionally show something like a rating. 
Updating the rating itself will be done by ajax.

Now i could convert the "showAction" to be uncached - which i would 
like to prevent...

Another idea might be to clear the FE cache for the plugins page each 
time the rating is updated. Doesn't sound good to me, too...

How would you realize this?

Kind regards, Jan
