[Proto-Scripty] Re: Ajax.Updater works only when html is on server where script is

2008-10-02 Thread Dave 

Thanks guys, I caught this:

While it is not possible to directly query websites for data due to
the same origin policy, the script tag does not honor the same-
origin policy and can be used in conjunction with JSON.

I'm assuming prototype is enforcing the same-origin policy then?

Thanks,
Dave

   Any ideas as to what I need to do?

You can add another script tag to your document, and point it to a
remote source other then your own domain, but that is not part of the
AJAX functionality provided in most libraries, including Prototype.
You would have to add a new script tag programmatically. It's a
different beast.
