How can I restrict number of Concurrent users on JBoss 4.0.4

Question

Jboss 4.0.4 GA Apache 2.2

Answer 1

OK, not very sure, but some googling led me to this:
Inside JBOSS_HOME\server\default\deploy\jboss-web.deployer\server.xml, look for the following.

Connector port="8080" address="${jboss.bind.address}"
maxThreads="250" maxHttpHeaderSize="8192" emptySessionPath="true" protocol="HTTP/1.1" enableLookups="false" redirectPort="8443" acceptCount="100" connectionTimeout="20000" disableUploadTimeout="true"

Modify the maxThreads parameter. Hopefully this would do the job.

Answer 2

Depends on how you want to handle the case when the limit is reached: Show a "please wait" page? Drop the connection? Hold the connection in a queue? I'd suggest to focus on:

1) Application / framework specific 2) acceptCount 3) maxThreads

Answer 3

It is probably better to reject the sessions at the front end (Apache 2.2 has a few modules to limit session count)
