UrlRewriteFilter can be used to set headers, if you do not want to write the code by yourself. http://wiki.apache.org/tomcat/AddOns ExpiresFilter is available in Tomcat 7 Best regards, Konstantin Kolinko - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

I don't believe Tomcat will mutate your Cache-Control headers so you are probably safe using a Filter. I can't really imagine another way to do this besides writing a Filter or Valve (without using a reverse-proxy as Igor suggests). - -chris -BEGIN PGP SIGNATURE- Version: GnuPG/MacGPG2 v2.0.17 (Darwin) Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Mozilla - http://www.enigmail.net/ iEYEARECAAYFAlCoShMACgkQ9CaO5/Lv0PDQlwCgxGbXPVOU65ug+BlGtkHdrUkm UjMAn2wb+lcntQBcp0O4LL3sOWRLxPm8 =Ib7m -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
