OsCache Newbie question

hi all,
I have 2 or 3 dynamically generated images in my jsp
page and i want them to be cached. I have statrted
using oscache. 
I tried using the 
<cache:cache key="myChartID" scope="application">
<embed ..... >
</cache:cache>

It does cache the image but the problem is the request
to the server via the '<embed ...>' is also executed.
In this case though the image is cached, the database
query is executed. This is precisely the reason why i
want to cache the image as the image generation is
costly.

Should i use the <cache:cache> tag or the CacheFilter
for this. 

I would appreciate any help in this matter.


Regards
Ashok Madhavan
