[RESOLVED] xmlHttpCreate function ie6 FAIL!

[MadManMcCann]

I'm trying to GET or POST a request to a server. The code below works fine in Firefox, Safari, Chrome and IE7+ but fails in IE6 in spite of the xmlHttpCreate function being copied and pasted straight from Microsoft's MSDN site. The place where IE6 fails is on the oReq.send() line. It appears to create an activeX object but just won't send it. I have also tried oReq.send(null) and oReq.send("") but neither works.


function _call(url){

oReq = xmlHttpCreate();
if (oReq != null) {
//oReq.open("GET", url, false);
oReq.open("POST", url, false);
oReq.send(); // <=============== this is where IE6 fails
return oReq.responseText;
}
else {
alert("AJAX (XMLHTTP) not supported.");
}


}

function xmlHttpCreate(){
if (window.XMLHttpRequest) {
return new window.XMLHttpRequest;
}
else {
try {
return new ActiveXObject("MSXML2.XMLHTTP.3.0");
}
catch(ex) {
return null;
}
}

}

Any help with this would be greatly appreciated.

Error message?

Did you use a tool such as Fiddler to see if a request goes out?

If you use POST then try passing the url as a parameter to send(), and call

httpRequest.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');

before send().

Thanks for looking at this for us :-)

Just tested with Fiddler:

Fiddler shows that the request did not go out.

We are really greatful for any ideas or help you can give :-)

Ohhh...by the way:

the error in IE6 is just "unspecified error" on line 57 char 4 which is the "oReq.send()" line.

We should have also given you a link to our test page:

Check in all GOOD browsers it's perfect then ie6 (client handcuffs) it just doesn't work.

Try using

return new ActiveXObject("Msxml2.XMLHTTP");

See if that makes any difference.

You are getting http status code of 122

You do not have to make an Ajax call to Flickr. You can do a JSONP call using the jsoncallback.

OK, so first and foremost - MASSIVELY greatful to you for your replies :-)

Now in responce to all of the above -

I've tried
return new ActiveXObject("Msxml2.XMLHTTP");
but decided to go with the Microsoft recommendation of
return new ActiveXObject("MSXML2.XMLHTTP.3.0");
(see http://msdn.microsoft.com/en-us/libr...8VS.85%29.aspx )
neither makes any difference

in reply to "You are getting http status code of 122"
I've tried both POST and GET. Both work in IE7+ and Firefox but neither work in IE6

in reply to "You can do a JSONP call using the jsoncallback"
I'm not using jQuery.
Our ajax call is made to a php script on our server. The php script makes the call to Flickr and returns the result to the javascript.
Since we are using Mootools to do the slideshow I'll investigate whether it has a similar function to JSONcallback in jQuery

THANKS AGAIN :-)

SOLVED!!!! The URL being passed to the Request object was too Long!!!! :-)

I am guessing you did not read that URL I posted that said it was a URL that was too long. lol
