before I start, I'm a developer, not a sysadmin (but due to size of the company I work for am having to take on this role as well), so apologies if I get anything stupid wrong.
I'm trying to get a number of different instances of our Rails app running on the same server, each with it's own subdomain, eg.
sales.mydomain.com as well as serving a static site from
Unfortunately, it's a Windows server (due to a Windows only 3rd party dependency). We're using Apache.
The setup I have at the moment oh so nearly works (for a while I actually thought it did).
I have two instances of the app running on ports 3000 and 30001, and the following virtual host setup at the end of my httpd.conf:
<VirtualHost *:80> ServerName mydomain.com ServerAlias www.mydomain.com DocumentRoot "C:/Program Files (x86)/Apache Software Foundation/Apache2.2/htdocs/website" </VirtualHost> <VirtualHost *:80> ServerName test.mydomain.com ServerAlias test.mydomain.com ProxyPass / http://localhost:3000/ ProxyPassReverse / http://localhost:3000/ ProxyPreserveHost On </VirtualHost> <VirtualHost *:80> ServerName sales.mydomain.com ServerAlias sales.mydomain.com ProxyPass / http://localhost:3001/ ProxyPassReverse / http://localhost:3001/ ProxyPreserveHost On </VirtualHost>
With this setup the static website works and I can reach both rails apps by going to their respective domains.
However, certain requests in each of the Rails apps do not work. I get an error like the following:
Proxy Error The proxy server received an invalid response from an upstream server. The proxy server could not handle the request GET /posts/4eaad77ec5b0d6569a3000054. Reason: Error reading from remote server
It's always the same URLs, and although I haven't been able to work out a pattern this (wild guess) sort of suggests to me it might be something to do with URL rewriting? Honestly haven't a clue.
Some examples of some urls that work are:

Thanks in advance for your help - I appreciate it.
