http.request(the_request)
}

raise "Response was not 200, response was #{the_response.code}" if the_response.code != "200"
return the_response.body
end

# this will fail with ArgumentError: HTTP request path is empty
s = get_html_content("http://www.google.com")
# these should be fine
s = get_html_content("http://www.google.com/")
s = get_html_content("http://github.com/search?q=http")
