Memory (RAM) is really your only practical limit when using session variables. Just make sure you make your session timeout a practical interval. and (assuming you are on CFMX) make sure you set both your max and default memory sizes to the same value in the CFADMIN. It's conceivable that if you have too many sessions going at once, you could use up all the available RAM and run into out of memory errors, but based on the limmited data you are storing in session, you will likely hit another bottleneck point (ie: CPU or DB connections) before your sessions exceed available RAM. > Also, is updating session variables all that much quicker than updating a > database.

Session variables are always going to be faster than making trips to the DB. -Cameron ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Special thanks to the CF Community Suite Silver Sponsor - CFDynamics http://www.cfdynamics.com Message: http://www.houseoffusion.com/lists.cfm/link=i:4:188912 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/4 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4 Donations & Support: http://www.houseoffusion.com/tiny.cfm/54
