TC 6 has the SemaphoreValve (http://tomcat.apache.org/tomcat-6.0-doc/api/org/apache/catalina/valves/SemaphoreValve.html) that you could sub-class to do mostly what you want (or for TC 5 under Java 5, grab the source and modify it). It doesn't prevent the number of theads that Tomcat spawns, but it limits the number that are executing through it at any given time (out-of-the-box, it would be the number of threads accessing the Context, but you can sub-class it and override the controlConcurrency method to make it finer grained). You could also look at the code, and do the same thing in a Filter. In this case, the 11th request will get queued, at least until the browser gets tired of waiting for it :). As Chris has already said, you can only limit the number of threads spawned at the <Connector> level. > Thank you. > --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
