Re: [Opensymphony-oscache] cachefilter

hi  ,
The matter is i don't know when to recreate the image, because the imagename  is cached in cache tag and it can't be obtained.
I still can't get imagename just by request parameter.
the code :
String  imageName = generateImage(request);
the generateImage(request) will consume some time  , so i  decide to cache it. but  its content can't be modified.


     Best Regards.

> You must check in the cache tag, if you have to create the image (again). Use the refresh attribtue of the cache tag and implement a new method "hasToCreateImage(request)" in you bean.
