Thanks for the hint.  ran into a few problems
web.Option.each failed
web.Option.methods  doesn't exist
changed to puts((web.methods - Object.methods).sort)
this yielded the following list
[]
[]=
_getproperty
_invoke
_setproperty
each
invoke
method_missing
ole_free
ole_func_methods
ole_get_methods
ole_method
ole_method_help
ole_methods
ole_obj_help
ole_put_methods
setproperty

Expeimented with the setproperty method

I used web.setproperty('Option', WinHttpRequestOption_EnableRedirects, 
false)

That did the trick.

Thanks again
