Limiting connections to Tomcat

Hi All,

I am using Tomcat 4.1.x and would like to provide a customized page error to the users when some thread/connection limit is reached. Now we are setting minProcessors="50" maxProcessors="375" acceptCount="10" on server.xml but can´t find a way to configure this error page.

I found mod_vhost_limit for Apache but again could not find how to configure this error page.

Any ideas?

First in tomcat's server.xml for your context there is a manager tag.  There you can set an attribute for maxActiveSessions.  When the maxActiveSessions is reached Tomcat throws and IllegalStateException.  Then I put in the web.xml of my webapp an <error-page> tag which catches the IllegalStateException and goes to a particular HTML.
Also a note you should use and HTML page or JSP with the session disabled.  When I first tried with a JSP it threw the IllegalStateException again and I didn't know what was happening but I guess JSP by default ask for the session.
Hope that helps, if I need to explain something better tell me.
