Track which mongrel handled a request December 26, 2007

I wrote a plugin which collects system information, and returns the data as HTML comments at the bottom of the page. When running multi-system / multi-Mongrel environments, knowing which server and Mongrel handled a request is paramount.
Unfortunately, getting a handle on this information is difficult, since ‘request.port’, ‘request.env['HTTP_HOST'], and ‘request.env['SERVER_PORT'], display the origin port, when your Mongrels are behind a reverse proxy.
Ezra clued me into a nice hack.You can add the following code to environment.rb, or in our case the plugin’s init.rb.
Apache mod_rewrite maintenance.html woes December 15, 2007
Posted by John Dewey in Apache, Configuration, Rails, WebServers.add a comment
Every self.respecting Rails site, has a configuring Rails with Apache section.
The recipe contains a mod_rewrite rule, allowing staff to dynamically enable or disable maintenance mode. The mod_rewrite rule, however, does not work on Solaris, OS X or systems with a ‘/system’ directory.
I have notified the Pragmatic Studio folks, and Charles (who wrote the documentation hosted at http://mongrel.rubyforge.org/). Below are further details of the problem, along with a solution. Hopefully the word gets out.
