问题
Our QA team reported that one of our applications is not working in Safari in Windows 7. After checking the problem we figured out that any postback event is not working. After some tries we found that Page.IsPostback() reports false and thinks it’s a first-time load of the page and postback did not include ViewState.
We tried many solutions including
ASP.Net postback problem with ViewState in Safari on Windows 7
Viewstate invalid when using Safari
ViewState Chunking in ASP.NET 2.0 (maxPageStateFieldLength)
but all didn't bring Safari to work.
There is nothing special about this application. It is normal pages that use one master page that is a very normal master page.
Any suggestions?

Safari has an issue when working with Windows Authentication under IIS if Negotiate provider is enabled so AJAX POST is not working.
How to resolve?
In IIS, go to the Authentication settings of your website. Right click on Windows Authentication, choose providers and remove Negotiate, leaving NTLM this makes everything works fine.

AJAX POST Request Only Works Once in Safari 5
Negotiate Mechanism article in Wikipedia shows that it is not implemented in Safari
