So when you go to ww...

Hi, I'm in need to get some integration work done in my ruby application. My main focus is web services and ActiveMQ integration (the systems I'm going to connect to are mainly written in Java).

I have a site with multiple subdomains and I want the named subdomains robots.txt to be different from the www one. I tried to use .htaccess, but the FastCGI doesn't look at it. So, I was trying to set up routes, but it doesn't seem that you can't do a direct rewrite since every routes needs a controller: map.connect '/robots.txt', :c...

In order not to block the reactor I would like to read files asynchronously, but I've found no obvious way of doing it using EventMachine. I've tried a few different approaches, but none of them feels right: Just read the file, it'll block the reactor, but what the hell, it's not that slow (unless it's a big file, and then it definitel...
