Web Tier Cache Folder Leftovers

rbuser

Is it expected to have numerous folders left in the web tier cache
folder after reports are run? Maybe it's a setting I'm missing?

I have a bunch of folders with one file remaining in them called time.txt.

For example,

{1AA38BA1-CB99-4CB3-8AA7-13CDD246F3FA}

rbuser

I should have noted: Delphi 2007 / RB Server 10.09

Each of the Guid folders represents a client sessions. The WebTier garbage
collector should be removing those folders and their contents, for an
sessions that have timed out.

For my test server, the folders get removed. I am using the latest version
of RB, 12.01. However I do not recall there being any issues with 10.09 not
cleaning up expired sessions.

This must have been something I was doing. I built a new web tier and
server from the demos and the cache folder is now clearing as expected.


This brought up several related questions -


Does a web tier session mean per user?

Then SessionOptions.MaxSessionCount = 25 would essentially mean 25
simultaneous users?

SessionOptions.MaxReportCount = 10 would then mean any single user could
run 10 separate reports in a single session before the oldest report was
purged out?

Finally, does SessionOptions.SessionTimeout = 120 mean a session will
expire after 2 minutes of inactivity or is that from when it was created?

Garbagecollect = true should then clean up any expired sessions the next
time a report is launched? Given the garbagecollect.minsleep minutes has
passed.


Thanks for your help.

> Does a web tier session mean per user?

Yes, the first time a user makes a request, a SessionID is generated, and
then subsequent requests include the SessionID, that is how the session is
tracked. The WebTier caches user session info by created a folder for each
SessionID.


Correct.


Yes. A user can run any number of reports, but only the last 10 would be
stored in the session cache, this is used to optimize performance.


Inactivity.


Yes. When the WebTier processes a request, it also invokes the
GarabageCollector - which removes expired sessions.
