If you mean "how many requests can Tomcat accept simultaneously?", then that depends on the value of maxThreads in your <Connector> (or the associated <Executor>, if you're using one). If you mean "how many requests will the operating system queue on top of those currently being processed by maxThreads?", then that depends on the value of acceptCount in your <Connector>. If you really mean "how many requests does Tomcat put in cache", then the answer is "Tomcat does not put requests in any cache". - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkshffYACgkQ9CaO5/Lv0PD4rgCfZHhz+JBKNOMVS5ZrqOCy4wJe HzIAoIT1NMxC5A89xBRUAATRrINIT/zf =5Obg -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
