In a .htaccess file, I have something like this to proxy Apache to Tomcat:
RewriteRule (.*) http://localhost:8080/tomcat-app/$1 [P]
All the redirects as well as internal links in HTML files are going to the Tomcat app directly, rather than to Apache.
So I would use ProxyPassReverse and the like to translate correctly, but apparently I'm not allowed to use that directive in a .htaccess file. I don't really want to put them into the master Apache configuration because that means rebooting Apache every time there is a change. Which is why I like the RewriteRole [P]: unlike ProxyPass, it can be put into .htaccess.
What can I do to simulate ProxyPassReverse in a .htaccess file? Or more specifically, without requiring reboots on any change?
