Setting up the proxy

To set up a reverse-proxy with Apache2, you first need to enable the Apache proxy module and virtualhosts. To enable the proxy module (mod_proxy), edit the Apache configuration file (Apache/conf/httpd.conf) and uncomment the following lines:

LoadModule proxy_module modules/mod_proxy.soLoadModule proxy_http_module modules/mod_proxy_http.soLoadModule unique_id_module modules/mod_unique_id.so

You then need to enable VirtualHosts. To do this, just uncomment the following line from the same configuration file:

Include conf/extra/httpd-vhosts.conf

Finally, you need to edit Apache/conf/extra/httpd-vhosts.conf and write in it the proxy directives.From the information you gave, they should look like this:

<VirtualHost *:80>  ServerAdmin ******  DocumentRoot "******"  ServerName *****  ProxyRequests Off  ProxyVia Off  ProxyPass /couch/ http://127.0.0.1:5984/  ProxyPassReverse /couch/ http://127.0.0.1:5984/</VirtualHost>

(+ some mLog directives and a few others).

-> Apache restart -> profit.

Learning Apache

You should have a look at the official documentation on the Apache official website or Apachetutor.org, though Google is, and always will be, everyone's friend.
