I am facing a lot of problems with Ajax xmlhttp object.

1. specified
xmlHttpObj.open("POST","http://" + location.host + "App_Data/DataFile.xml", true);

it throws an unspecified error when i try debuggin using the debugger;

If i disable the javascript debugging in the browser it thorws 403 forbidden error.

I am using IE 7

Can anyone guide me here?

FYI

I dont know if the ActiveX objects are precent in my browser or not.
Can anyone tell me how to check without using following code for ActiveX objects?


    function CreateXmlHttpRequestObject(){
        if (window.ActiveXObject)
        {
            try
            {
                xmlHttpObj = new ActiveXObject("Microsoft.XMLHTTP");
            }
            catch (e)
            {
                xmlHttpObj = new ActiveXObject("Msxml2.XMLHTTP");
            }
        }
        else
            xmlHttpObj = new XMLHttpRequest();

            return xmlHttpObj;
    }

Are you not missing a "/":

xmlHttpObj.open("POST","http://" + location.host + "/App_Data/DataFile.xml", true);

If you are getting a 403 error this means you do not have permission - this usually means that anonymous access is turned off and the users current credentials aren't being sent automatically.

Yeah i was missing a slash there. HOw can we get the permission setting done?

 However the other problems here are

1. xmlHttpObj.readyState is always 1 & never is set to 4
2. I dont get any value for responseText ir respon****ML

If you are using IIS then you set the permissions in IIS Manager on the security tab.

insede the IIS i see only

Directory security. I tried playing around with this invain.

IIS --> Default Website --> XMLHTTPObject --> properties --> Directory Security

I'm i missing something here?

That's right - click on the Edit button next to "Authentication and Access Control" and make sure "Enable anonymous access" is ticked.

If that is ticked then the anonymous user does not have permissions on the files, in which case go in an set the security on the file in Windows Explorer.

i tried ticking this option with username and password set as well.

Also shared this website and enabled directory browsing.

Still doesnt work :(

If you're still getting the 403 error then its the windows security you need to fix - set it so Everyone has read access to the files.

I always try to test access to the directory in Firefox - if it prompts you for a username/password then you know anonymous access is borked, otherwise its usually windows security.

I tried in windows ... no luck

Other hint is .. when i try accessing the file directly by right clicking on the solution explorer --> view in browser, it

it....
