Some AJAX responses result in a file not found error!

With IE a certain ajax call doesn't return results but it only happens sometimes and not always.

The server error log shows: File does not exist: /home/user/public_html/500.shtml

The following are the http headers sent. The first is an AJAX call without an error and the second is with the error. I have changed any data that would identify the website. What on earth could be wrong?

they are the same ajax call.

Well what's the JavaScript code? Also, what's the URL with issues? Usually IE will fix silly little URL mistakes, and FireFox will not. So it's strange to me you're having this problem.

Also, what's the version of IE?

Do you think it is a url problem? The code is quite long for me to post it here but I will look into it. I was using jquery and getting that error with both IE7 and IE8 but FF was perfect. I decided to remove jquery and make my own ajax function and it "solved" the problem. But I wonder why? This was the jquery code:

Code:

$.ajax({

       type: "POST",
       url: "ajax/"+file,
       data: url,
       success: function(returneddata){
         
            setdata(container,returneddata); // puts the returned data into the container element
          
       }

     });

I used alert boxes to see what the file and url variables hold just before they are sent to that jquery function, and they seem ok, even when the error happens. The file would always be a valid file and the url would always be qid=56 (or some other number). So I don't understand what is going on

Do any of you know of any issues with the jquery ajax function?

You have already answered to yourself.

Most of the time frameworks bring troubles. It is by far a better choice to create your own codes, if you are a good coder, than to use a framework. One usually does pay for his laziness

The people who make these frameworks are meant to be good coders. Aren't they meant to test their code on multiple browsers?

I guess it is easier to debug your own code than a framework.

They are excellent coders. But they want to build un universal javascript tool. A sort of panacea. Or a miraculous javascript interface for fools. Which, obviously, woun't work for all the needs, because it is impossible to predict all the humans needs. And a fool woun't understand an interface, as long as he does not know the language itself. Simple.

If you know javascript, you can write your own codes. If you don't, a framework woun't help you too much. Simple.
