Pound reverse proxy and simpler URLs for webapps (Sickbeard, Plex, CouchPotato, Headphones, SABNZBD)

I run a plethora of local web applications that each listen on different ports, and I wanted to simplify their URLs so I could just type a hostname to access them:

Hostname mapping
Application	Default URL	Desired URL
Sickbeard	http://linux-server:8081	http://sickbeard
SabNZBD	http://linux-server:8080	http://sabnzbd
Nagios	http://fw:1008/nagios	http://nagios
Plex Media Server	http://media-server:32400/web	http://plex

Turns out, this is really simple to do by installing Pound, but it took me some time to piece together how to configure it for Plex and Nagios, which have both a port number and a path mapping. Basically, the recipe is that you first redirect the URL path portion, and then you do the host/port redirect. Plex has an additional issue with some javascript in the web interface that causes a loop unless you put in a rule to detect a particular header text (X-Plex-Device-Name) to avoid remapping the /web portion of the URL.

Here's my pound.cfg configuration file for future reference (obviously, this requires that you've set up your DNS/hosts to point all the aliases like sickbeard, plex, etc. to whatever host is running pound)
