impact of CLIENT_STATE_MAX_TOKENS ?

[hanasaki jiji <ha...@gmail.com>]

What other impact is there if a low value is set?  Just cannot use the
back button?  We are thinking of lowering this number to shrink the
httpsession size... also when does an expired token's serverside data
get removed from the httpsession?  is it the token expired on the
client/browser and then the next hit to the server removes it from the
server cache?

org.apache.myfaces.trinidad.CLIENT_STATE_MAX_TOKENS
In "token"-based client-side state saving, chooses how many tokens
should be preserved at any one time. The default value is 15. When
this is exceeded, state will have effectively been "forgotten" for the
least recently viewed pages, which can impact users that actively use
the Back button or that have multiple windows open simultaneously.
Developers building HTML applications that rely heavily on frames will
likely need to increase this value.
