You should really try this yourself before asking here:


C:\Documents and Settings\cmcmahon>irb
irb(main):001:0> $base_url = "http://www.google.com"
=> "http://www.google.com"
irb(main):002:0> $about_url =  "/intl/en/about.html"
=> "/intl/en/about.html"
irb(main):003:0> full_url = $base_url + $about_url
=> "http://www.google.com/intl/en/about.html"
irb(main):004:0>

also, those global variables are going to cause you trouble sooner or
later.
