Is that possible to call to external PHP script from Ajax?

[Axel13pl]

I'm trying to call to external PHP script using Ajax like this:\[code\]$(function() { $.ajax({'url': 'http://stokes.chop.edu/web/zscore/result.php', 'type': 'POST', 'success': function(response, textStatus, XMLHttpRequest) { alert('[' + response + ']'); }, 'error': function(XMLHttpRequest, textStatus, errorThrown) { alert('Error'); } });});\[/code\]The result is: \[code\][]\[/code\] (i.e. \[code\]success\[/code\] function is called!),but I see the following error in HTTPFOX plugin for FireFox: Error loading content (NS_ERROR_DOCUMENT_NOT_CACHED)What's wrong with my code ?
