EDIT (was same reply as Pit gave)

I don't have WinHttp on this machine so I can't check this.

(( web.Option[6] = false ))
If WIN32OLE is using the hash notation to access attributes,
there would be a problem with a method called '6' (illegal).


You could try examining the Option object with something like:

  web.Option.each { |opt| p opt }  #  might not have an 'each' method

Use Ruby's "introspection" to nosey around and see what's available:

  # may be useful to quote on this newsgroup
  p web.Option.class
  puts '=========='
  puts((web.Option.methods - Object.methods).sort)
  puts '=========='
  puts((web.methods - Object.methods).sort)
  puts '=========='

  # If (e.g.) 'ole_methods' is in the list
  puts web.ole_methods


I'm fairly confident with Ruby but I always have to mess around
trying different hacks with COM objects.  Someone who uses them
twice a year is in much the same position as a COM newbie.
