[Resolved] AJAX "Access is Denied" Error

AJAX "Access is Denied" Error

I am attempted to make a firefox add-on that will send data to an external server (sort of like those stumbleupon and del.icio.us addons) with information about what page you're on. however, i want to do this with ajax rather than with forms. The info is populated with predefined variables and are populated with prompt / other info.

now, my problem is that since i'm trying to send the data to an external server, my ajax keeps returning an "access is denied" error. (i actually spent a really long time figuring that out - firefox didn't give any errors since it was an extension... i eventually had to make a new file of jus the ajax to test it in ie so i could see the exact error.)

i tried changing the chmod of the files on my server to 777 and i still got the access denied error. is there some way to get it to work?

or will i have to like open a new window with a page from my site and let them do their stuff there? (since thats what those social bookmarking sites seem to do... i think... but all of the windows look similar if not the same just a different header, so im not so sure).

thanks



EDIT:
I found the solution at
http://developer.mozilla.org/en/docs/Cross-Site_XMLHttpRequest

All it took was adding:

<?php header('Access-Control: allow <*>'); ?>

to my php file that was doing the processing.

However, i believe this only works for the newest browsers, but since I'm writing a firefox addon i can just make it for firefox 3.0+ (since this is what i believe it works on)

I have never worked with Firefox addons.
However, in conventional Browser JavaScript, you may only use Ajax to access a file in that site.

For example, a script on www.bruce.com couldn't open something from www.anothersite.com. Attempting to do so would throw a forbidden error.
(Interestingly enough, even calling http://bruce.com/file.php isn't possible from http://www.bruce.com/script.js. Even the subdomain must be the same.)

Is there a chance that Ajax is not the tool you should be using? You may want to research different methods of Firefox addon data retrieval.

I see. Well, firefox addons are basically XML to make the menus, which call javascript functions with oncommand (aka onclick, etc). so i think the only way to do it would be with javascript... what other ways are there to send data to and from external servers since ajax won't work? i only know th ebasics of javascript, and am no pro.

Found the solution and edited my first post with the answer for those who might have the same/similar question.

Thanks everyone.
