http = Chilkat::CkHttp.new()

#  Any string unlocks the component for the 1st 30-days.
success = http.UnlockComponent("Anything for 30-day trial")
if (success != true)
    print http.lastErrorText() + "\n"
    exit
end

#  Send a HEAD request to get the response header:

# response is a CkHttpResponse
response = http.GetHead("http://www.chilkatsoft.com/download/ChilkatDotNet2.msi")

if (response == nil )
    print http.lastErrorText() + "\n"
else

    #  The ContentLength property of the HTTP response is
    #  the size of the remote file:
    print "Size of download = " + response.get_ContentLength().to_s().to_s() + "\n";
