help

I am running tomcat on centos6. I'm trying to configure Apache as a front end to tomcat so I could access:

help-test.example.com:8080/4-3/help
help-test.example.com:8080/4-2/help
help-test.example.com:8080/4-1/help

via:

help-test.example.com/4-3/help
help-test.example.com/4-2/help
help-test.example.com/4-1/help

with below apache configuration it is working:

VirtualHost *:443>
LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_http_module modules/mod_proxy_http.so

ServerName help-test.example.com:443
ServerAdmin webmaster@example.com

ProxyPass / ajp://127.0.0.1:8009/
ProxyPassReverse / ajp://127.0.0.1:8009/

ErrorLog /var/log/httpd/error-ssl.log

RewriteLog "/var/log/httpd/rewrite-ssl.log"
RewriteLogLevel 3
/VirtualHost>

VirtualHost *:80>
ServerName help-test.example.com
Redirect / help-test.example.com /VirtualHost>

but one more thing needs also to be done when I access :

help-test.example.com/help --> help-test.example.com/4-3/help

I have tried to add:

RewriteEngine on
RewriteCond %{REQUEST_URI} !^/help/
RewriteRule (.*) /4-3/help [L,NE,R]

getting an error:

RewriteCond %{REQUEST_URI} !^/help/
RewriteRule (.*) /4-3/help [L,NE,R]

You are getting a redirect loop here because you are saying that if the URL is not /help/ then redirect to /4-3/help (etc, etc, ...). You need to reverse the logic and only redirect when it is /help/.

Change to...

RewriteRule ^/?help$ /4-3/help [R,L]

NB: This is a temporary (302) redirect. Change R to R=301 to make it permanent.

EDIT: There appeared to be something that was appending a trailing slash to the request before the rewrite was processed, so the RewriteRule pattern needed to be changed to ^/help/$ (the ? was omitted since the directive is being applied directly in the server config).
