How to disable portlet caching in JSR168 portlets?

[John Zwick]

I have 2 pages in my portal that points to the same portlet (but with different portlet preferences). I have an issue where the page gets cached and when you click between the 2 pages, it doesnt reload properly with the updated portlet preferences. Is there a way I can disable caching? This is in Websphere Portal 6.1.

Thanks!

Use the following line in doView method:

rRes.setProperty("expiration-cache","0");

and also can use<expiration-cache>0</expiration-cache> in yours portlet deployment descriptor.
