Subject [users@httpd] Apache/2.2.12 Reverse Proxy
Date Tue, 08 Jun 2010 06:28:47 GMT
Dear all,
 
I am having JSP page redirecting problem with apache reverse proxy and
have been troubleshooting it for a month already. I really hope someone
may englighten me in this thread. Really appreciate and thanks.
 
The infra is setup as:
 
Internet <--> Apache2 Reverse Proxy <--> Tomcat
 
1. The apache2 is purely configured as a reverse proxy server and it's URL
is http://10.0.0.7/abc/mysite/
 
2. The Tomcat is setup to host the JSP website internally, and its URL is
http://192.168.0.60/mysite/
 
With the configurations given below, it maps to the internal url nicely. I
can see the JSP website by http://10.0.0.7/abc/mysite/
 
However, when I click on hyperlink on the website that does internal PAGE
REDIRECT, the browser could not display the page. Apparently, the page
redirect action breaks the reverse proxy.
 
Did i miss out anything?
 
My reverse proxy config:
