[support] how to shrink sessions table

[Laura Scott]

We have one site that is on the busy side and the sessions table is  
getting, shall we say, on the largish side (303k records). I'm  
looking at reducing that. I'm assuming this would be done in  
settings.php.

ini_set('session.cache_expire',     200000);
ini_set('session.cache_limiter',    'none');
ini_set('session.cookie_lifetime',  2000000);
ini_set('session.gc_maxlifetime',   200000);


My question: Which of these settings should we cut down to reduce the  
number of records? (We don't want to log people out upon closing the  
browser, so that approach is out.)

Would I cut down the cookie_lifetime?

Any help would be much appreciated. Thanks!
