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 ..
