Calling REST web services from a classic asp page

I'd like to start moving our application business layers into a collection of REST web services. However, most of our Intranet has been built using Classic ASP and most of the developers where I work keep programming in Classic ASP. Ideally, then, for them to benefit from the advantages of a unique set of web APIs, it would have to be called from Classic ASP pages.

I haven't the slightest idea how to do that.

You could use a combination of JQuery with JSON calls to consume REST services from the client

or

if you need to interact with the REST services from the ASP layer you can use

MSXML2.ServerXMLHTTP

like:

Set HttpReq = Server.CreateObject("MSXML2.ServerXMLHTTP")
HttpReq.open "GET", "Rest_URI", False
HttpReq.send

@KP

You should actually use MSXML2.ServerXMLHTTP from ASP/server side applications. XMLHTTP should only be used client side because it uses WinInet which is not supported for use in server/service apps.

This is quite important, otherwise you'll experience your web app hanging and all sorts of strange nonsense going on.
