uncaught exception: permission denied to call XmlHttpRequest.open

121 100+

hello

I am using xmlHttpRequest method in my application, this method is giving problem in the following browsers

1) Internet Explorer 7
2) Mozila Firefox(2.0.0.16)

I got solution for Mozilla issue

let me explain what i did

In the about:config (for this we have to open browser and type in the address bar as about:config, after that in filter place type as signed) of mozilla brower
you need to set 'signed.applets.codebase_principal_support' to true and add the line

'netscape.security.PrivilegeManager.enablePrivileg e("UniversalBrowserRead");

in my script(means above xmlHttpRequest.open)

But I am facing this issue in IE7 there i am getting Permission Denied to open xmlHttpRequest.

Anybody knows solution for this problem

i guess you want to start a 'cross-domain-request'? it is generally a very! bad idea to rely on settings to a browser-config ... unless it is an intranet application. you may probably find this helpful?

kind regards

 var xmlHttp = null;

if (window.XMLHttpRequest) {

  // If IE7, Mozilla, Safari, and so on: Use native object.

  xmlHttp = new XMLHttpRequest();

I quite agree with gits. You probably want to make a cross-domain requests. Could you post more code for detail?

Hi, would you please tell me the value of "getldap_username_utility_url" ?

You can use a web proxy for cross-domain requests. Another alternative is a dynamic script tag.

I'll just point out that dynamic script tags are for JavaScript/JSON only, so may not be useful here. One other alternative is Apache's mod_rewrite, if that's possible.
