Before my message goes down too much, I found some useful information from the website: http://howtoforge.com/apache2-mod_ruby-with-ispconfig-2.2.20-and-above Basically, I need to configure my apache server so that it will execute ruby script instead of return the whole script back. I followed the example and it works. So this solves my second question. However, for my case, I still need to parse the parameter in the URL, i.e. in http://www.mysite.com/sum.rb?a=3&b=5, how can server knows a=3, b=5?
