This is a well known issue with Web-Kit based browsers but was fixed with the latest version. Which version of Safari are you using?

Have you tried this fix?

Hi Gnanasekhar,

I have the same problem, with the exact same Safari version - Did you come up with a solution for this?

Hi Delmont,

I didn't find a solution with update panel,

So i removed update panel and replaced autopostback controls with html controls, update server object model with ECMA.

Now its working in all browsers.

I think this problem occurred when we have implemented only Windows Authentication for the web application, let try to add dummy Form authentication in this web application too (select form authentication and enter dummy membership provider), the sign in page will show you, select Windows Aurhentication.... You will see you application work well for all browsers.

Next if you need only Windows Authentication you can create custom the sign in page to bypass to Windows Authentication "/_windows/default.aspx?.." only.
