Something like: JkMount /LCSW/*.jsp ajp13 > I tested the above in a test environment and was able to access a > gif file with tomcat down. Try the above. I think you'll like it better, since you won't have to add exceptions for every type of static file you want to serve. > my question is, how does the ajp13 connector interpret a gif > file/static content request as opposed to a jsp request? mod_jk does not do any interpretation at all. The JkMount directives just set up a table of URL pattern matchers. No content is analyzed or anything like that. In combination with another module, you might be able to sniff some of the /request/ and then conditionally invoke Tomcat (by using André's favorite "SetHandler jakarta-servlet" trick) but that would be considered super-human efforts to do something that ought to be simple. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkodTrgACgkQ9CaO5/Lv0PAZLACgwBc8vKC66xVRYrd+HJoYtmcf sKwAn0bx7DlKzROMeIV0zhjQ/VSXB0zc =Sxs5 -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
