Once configured, mod_jk and mod_proxy_ajp work in exactly the same way (at least, the wire protocol is the same -- the modules are obviously working somewhat differently, internally). Basically: worker.foo.host=tomcat worker.foo.port=8009 + JkMount /myapp/* foo is the same thing as this: ProxyPass /myapp/ ajp://tomcat:8009/myapp/ ProxyReversePass /myapp/ ajp://tomcat:8009/myapp/ mod_jk's older configuration uses a separate file to configure the workers, then JkMount directives in httpd.conf in order to map URLs to those workers. mod_proxy_ajp's configuration is done all in httpd.conf and matches the configuration of all mod_proxy_* modules. The configuration becomes more complex for both modules when using load-balancing. mod_jk uses a single worker of type "lb" with other workers actually connecting to Tomcat instances, then you use JkMount as usual with the "lb" worker, so httpd.conf need not change at all to introduce load-balancing. mod_proxy uses a <Proxy> directive to define a balancer with various BalancerMember directives and then uses a ProxyPass directive to map a URL space to that balancer, so httpd.conf becomes more complicated when load-balancing is introduced. Note that you can configure mod_jk entirely within httpd.conf if you want, using JkWorkerProperty. I don't believe you can configure mod_jk using such compact syntax as mod_proxy supports, yet mod_jk does support "template" workers which can significantly simplify your deployment if you have many workers to track. Hope that helps, - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.17 (Darwin) Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with undefined - http://www.enigmail.net/ iEYEAREIAAYFAlDtjQMACgkQ9CaO5/Lv0PC8xACfaXUc/Xl7sGU+Rh/eURxxChtd lR4AnjejrpdNTeExDevJ3eAkuTUN0m7g =nFLK -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
