Subject Advantages of using apache+tomcat formerly -> Re: server.xml (with mod_jk configuration) being rewritten
Date Sat, 17 May 2003 19:17:38 GMT
thanks for the response jacob, now going in different direction :

what is the advantages of using redirection  from apache (besides load 
balancing and using static content) and how most people are using it? Do 
they use tomcat only or Apache and tomcat?
