Uh, how?

  There was RSExecute, claimed to work with IE3+ and NN3+. IE4 implemented XML Data Islands with Java Applets, anyone could do it. MSXML XMLHTTP was ActiveX component, as was one of the crossorigin tools - Flash, anyone could do it. I have to check JSONP support.

    > anyone could do it Plugins like flash and java applets were non-starters for many enterprises. XML Data Islands, as I recall, did not do any network requests. They were chunks of XML. Anyone could not do network requests with XML Data Islands. RSExecute... I looked it up. Ok I stand corrected although it is not clear when that was released for IE. JSONP? What? JSON did not exist back then. Are you trolling?

  JSONP, or the iframe equivalent. I know, you're thinking JSON didn't exist back then, I must be trolling. I'm not, and it did! JSON is short for "JavaScript Object Notation". With rare exceptions, it's valid JavaScript already! So JSONP only needs pure JavaScript, nothing else. However, back then it wasnt necessary to use object notation at all. As it was returning a script to run, the script could just call functions directly instead of assembling an object. Aside from JavaScript, people also used a Java applet or Flash to do the communication (faster than JSONP) as most browsers had at least one of those installed. Java and Flash could both be called from JavaScript.
