Dont cache a variable in action


I m facing a unique problem. I have a method which i m caching through
caches_action but in that i have one variable which i dont want to

To be specific i m using paging and if i cache the page my pagination
stops. I m using custom pagination method.

Can ne one tell me how to solve this issue. Is there a way i can make it
possible not to cache one variable in a method. Sounds odd but I dont
have ne other option in my mind
