Demonstrates Rest.FullRequestNoBodyBd, which sends a request with no body and stores the binary response body in a BinData.

The file paths are relative to the application's current working directory. Absolute paths may also be used. Supply the paths appropriate to your own environment.

require 'chilkat'

success = false

rest = Chilkat::CkRest.new()
bTls = true
bAutoReconnect = true
success = rest.Connect("example.com",443,bTls,bAutoReconnect)
if (success == false)
    print rest.lastErrorText() + "\n";
    exit
end

#  FullRequestNoBodyBd sends a request with no body and stores the binary response body in a
#  BinData.  This is appropriate when the response is binary, such as an image or file download.
