Gluster users - Sep 2009 - performance/io-cache translator question

Hello all,

can I tell the io-cache translator to _not_ cache a certain type of file?
Maybe with a special priority or by simply not adding it to the option
priority line?
Lets say I know it is good to cache "*.h" but useless to cache
"*". How would
I configure that?
