cvs commit: jakarta-tomcat-4.0/catalina/src/share/org/apache/catalina/session FileStore.java
kief 01/04/14 03:56:29
Modified: catalina/src/share/org/apache/catalina/session
FileStore.java
Log:
Removed code which duplicates that in Manager, namely the background
thread checking for expired sessions. This involved removing implementation
of the Lifecycle and Runnable interfaces.
Also changed the log method to indicate messages as comming from FileStore
rather than Manager.
