[users@httpd] Tuning tomcat4 and expression matching with apache

[Sanjay Saha <sanjaydotsaha@xxxxxxxxxxx>]

Hi List,
 
 I have a specific question about apache _expression_ matching.
 
 I have a apache tomcat server setup . While tuning tomcat i needed to achieve some tweaking to the apache _expression_ matching , or atleast that i 
 felt .
 
 The site have all incoming urls (www.subdomain.domain.com type) are redirected to  (https://domain.com/subdomain/index.jsp) .
 
 The possible input urls are: 
 
 www.aaa.domain.com ( mostly )
 aaa.domain.com
 http://aaa.domain.com
 www.domain.com/aaa/
 
 And the redirecting url are :
 
 https://www.domain.com/aaa/index.jsp (mostly )
 or
 https://www.domain.com/aaa/ 
 
 The above redirection is working and valid for the following apache directive :
 
 <VirtualHost *>
 ServerName aaa.domain.com
 RedirectMatch (.*)\ .*$ https://www.domain.com/aaa$1
       ------x-------
 
 Now for load balancing i needed to change certain direct
 ives
 related to Mod_JK . The modifications at (httpd.conf) needed as below :
 
 original :
 JkMount /* my_workers 
 
 Modified to :
 JkMount /*.jsp my_workers
 
 --------x-----
 
 The change really worked .., the site started operating with tomcat serving its content alright . The subdomain functioning just stopped.
 
 The scenario here : 
 at the ServerRoot ( /ust/local/domain/ ) the "index.jsp" resides . At that "index.jsp" a mapping is confirmed , which gurantees that the http get request ( when someone tyies to connect www.aaa.domain.com ) with "aaa" subdomain is served as index.jsp with the specific dynamic content part defined for "aaa" subdomain . This way multiple subdomains are entertained . So there is no "aaa" directory or "aaa" filename at ServerRoot . The related jsp for "aaa" is placed somewhere else as per "index.jsp"
 
 Let me know how exactly to overcome the situation .
 
 Because after modifing the httpd.conf en
 try as
 above i started getting 
 errors :
 
 error.log :
 Files does not exist 404 /usr/local/domain/aaa
 
 access.log :
 
[aa.dd.bb.cc] - - [22/Mar/2006] "GET /aaa HTTP/1.1" 404 346 
"-" "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; PCQuest)"

 Let me know where i am mistaking ..
