Re: [CODE4LIB] Lost thread - centrally hosted global navbar
Okay, yes, thank you for clarifying! I think the opening line of Wikipedia's CORS page [1] is a little misleading. So I can load the js in my page from a different domain, but I can't use javascript to grab content / data from another domain -- and that is where CORS / JSONP would come in. Correct? The last time I was working around that issue standard practice was for the js to call a script on your own server, which then went out and grabbed the data for you.
