Hi All,

the AJP thread pool has a maxSpareThread setting (i.e.
doesn't this have an effect without pool timeout?)?
What could be the reason for SYN requests of the Apache that never get
answered by Tomcat?

Basically this works, if you put a webapp context called ROOT into the

You should have a look at the Tomcat default installation.
