Hello,

i've run into a problem which drives me really crazy.

After 4 hours checking / searching i don't know where i can search for this problem anymore...

I would be really happy, if someone can help me further soon!

SOMETIMES!, so not every request, the request seems to be send twice, But it's not really send twice?!!

• Firebug show the request twice (but the first one not completed), in the first one the X-Request-With Header would be set

FIRST request header:

• in Live HTTP headers i cannot see that the first one goes out or even get a response.

• The Apache Log shows only one request (the second one, but also no redirect or anything else, otherwise i should see that in Live HTTP headers)
• because i run into an error without this header in my custom PHP error log i see also the second one

Further i thougth that i could log both request in a local JS variable, but that even doesn't work:

var requestsLog = new Array();
requestsLog[requestsLog.length] = $.ajax({
url : loadUrl,
				type : ajaxMode,
				data : this.formData,
				dataType : 'json',

				headers: {
					'X-Requested-With': 'XMLHttpRequest'
				},

....

});

I also see only the second request. As you might have seen above, i'm also trying to forcing the header "X-Request-With".

So the header should always get send.

Some more information about this problem:

• the webserver stands in austria
• the problem first time occured when accessing the service from america (accessing over the intranet)
• downgrading vo 1.5.2 also didn't helped, the error then goes further -> because i run into an error and for me in PHP is a normal request i send the plain error HTML page and afterwards all Javascript files are loaded again with an XMLHttpRequest?!?
• JSlins also didn't show errors in my code
