Hello, I'm using firefox 46.0.1 for my javascript application. I have wrote a AJAX logout function, which is using BASIC Authentication for logout my application. But it will not allow to logout completely, after refresh the page it allow user enter into application. But the same code works on firefox 45.0.2 and all the other browsers. Can you please help me, how to resolve this. I want to pass wrong credentials to logout. Below is my code: $.ajax({ type: "GET", url: EndPoints.Index, async: false, username: "advanced", password: "xxxxxxxxxxx", headers: {"Authorization": "Basic authentication"} })
