Where does the server hang? On logins?

Does Tomcat eventually log anything suggesting that there is a successful connection? - -chris -----BEGIN PGP SIGNATURE----- Comment: Using GnuPG with Thunderbird - https://www.enigmail.net/ iQIzBAEBCAAdFiEEMmKgYcQvxMe7tcJcHPApP6U8pFgFAl6DfaUACgkQHPApP6U8 pFgWcg/7BufYygaJeerkpwGuCXafQ9f/xTFTPevvgfL2PSD9/iZiYm7vOTWXqwrP 7xn8XRUEmycNROq31pfFyfDP8IJqlrRwampEoRRzVbQDXwBdeNDHlFILL7+BVrvP 0q9Wgb9WdWlPuVv/ZYMM5GLRVxhoCX68p0tRlmxpOM/U4Uiaa9eDR809GCliNWa9 +QThei2UewGfOsIQovpSU76qUuSnmcIf2iy6UJ2DkKH7mLmbyX58WW3JAX4Y1kPY CV1jUVQ58KRcqD3bgHrEarMkAWI6AhgrXFf6MaqC8z0NPykPmeiwfAl4JY3kkUsU LmxzJqfQoztv+NJdcsBwjV+hA81zeeAP/6NfV/q1kTocHYYea5wKSJXRFFbGUeh/ STAu2pw5yA43tZvW9Nthn2SJS1lC7XMs/izi95J+srxjxedMg3i/NfkBiaf78i42 GXnjxNIi8GBPTQZ4hEL83p8Jn1r0jd/13zCUSAcpiV8svTBlWhqPelVXti4fuL41 ssqpAmhe4A0lUDnnpiGZHld57oA5K3FJ46c6PRhjR5hu9/nQig3d3cZuqFlimnwK 79PeLquSewFTNDOVbJhhYsQzPgMOFNejo50E88AVQWIWMDqAtEzFZ87LFlLjq3cI Hek1jV4PMpDjnaJNERJdzRMSAhXdyu5JIjkia3+s/d8B8Q+htR4= =c9iM -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
