I am getting the following error: jquery ajax readystate 0 responsetext status 0 statustext error when giving it: url(http://www.tutorialspoint.com/proto
same origin policy. the browser does not allow when you're on
http://site1.com
to connect to:
site2.com
sub.site1.com
site1:99.com
https://site1.com (not sure about this one)
This is so site1 cannot steal content from site2 and pretend it's the content of site1. Ways around this is JSONP (google maps use that I think) and having site2 provide cors headers but cors are not supported in jQuery 1.* (maybe not in 2.* either) because IE has some problems implementing it. In both situations you need site2 to cooperate with your site so your site can display it's content.
If you only use this yourself then you can use Firefox and install the forcecors plugin. To activate you can choose view => toolbars => add on bar and click on the text "cors" in the right bottom of the screen.
