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.so
LoadModule proxy_http_module modules/mod_proxy_http.so
LoadModule 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.
