I am trying to develop a system where if a user hovers over a particular link, a little tool-tip box (just a div) will show up, show a 'thinking' graphic if need be, and grab a specific chunk of text from our wiki. I've got the text in the wiki in a unique wrapper, I just don't know how to execute the actual grabbing process. Is this possible with j/s? What else should I look into from here?
I’d personally use PHP or an Apache Proxy (page 2 in the above link).
Nope, I'm not sure if he is talking about wikipedia.org or not. Now that you bring it to my attention, I admit I'm probably wrong in regard to that. However I do know he's working with an external domain as it is mentioned in the thread title so therefore the rest of my post should still be of some additional guidance on top of your initial post.
Two subdomains would encounter a permission denied security error. "Two sites" is a better way to word it. Should I call it a cross-site permission denied security error in the future? It sounds funny but defiantly more accurate
