Answer 1

You could simply add the given lines in the httpd.conf after enabling the proxy modules.

ProxyPreserveHost On
ProxyPass /EMBackend http://localhost:8080/backend/mvc
ProxyPassReverse /EMBackend http://localhost:8080/backend/mvc

Just restart the server and you are done.

I found a working solution:

Enable:

LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_http_module modules/mod_proxy_http.so

Put this in the main section of your configuration (or desired virtual host, if using Apache virtual hosts):

ProxyRequests Off
ProxyPreserveHost On

<Proxy *>
    Order deny,allow
    Allow from all
</Proxy>

ProxyPass /EMBackend http://localhost:8080/backend/mvc
ProxyPassReverse /EMBackend http://localhost:8080/backend/mvc
<Location /EMBackend>
    Order allow,deny
    Allow from all
</Location>

So I guess I can't put it in .htaccess or I had to set ProxyPreserveHost On. I put Include conf/extra/ in the httpd.conf file and created the httpd-proxy.conf file and put the script above in it. Restarted apache and it's working!

In very modern apache, turn on proxy by:

a2enmod proxy;
a2enmod proxy_http
