hi : Thanks a lot for all the information. in fact my http://portal.example.com is a liferay portal server. i need a canonical hostname because liferay need it to function 100% correctly.
Finally i choose to use tomcat+urlrewritefilter, and i found that liferay+tomcat bundle already include urlrewritefilter to do some filter things. so i just need to add the canonical hostname rule to it. I was hesitate because i saw somebody complain about the speed of urlrewritefilter. but i didn't notice speed difference after i apply the rule. thanks again for all the suggestion. i am a happy administrator now. --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
