session data is currently 500bytes to 50k, depending on what i'm preloading for the user

using bzip or gzip compression on session File, the 50k becomes 900bytes

i'll have to bench what perl can do in time and filesize. i guess my options would be either compress the files before/after apache reads/writes them, or if i'm using a bdb or memory store, serialize the data then compress it before putting it in the store.
