Subject Re: Tomcat 4 unpacking of WAR files behavior
Date Thu, 01 Mar 2001 21:51:41 GMT
Remy,

What I am trying to do is start a discussion of _what_ the behaviour should be,
so it can be fixed. I already consider the current behaviour to be broken.

For example deploying a war on starutp, then undeploying it on shutdown
adds unnecessary overhead to the tomcat start/stop processing.  This would
be a huge issue in a hosting environment where you might have 100's of war
files.

Regards,

Glenn
