I have an ASP.NET Web Application using .NET Framework 4 and it is working fine on all browser when I test it locally using my Visual Studio Pro 2010, but when we deploy it to our server (IIS7 on Windows Server 2008 R2), the LinkButtons of my Web Application is not working correctly on Safari Browser on all platforms.
What was happening was when the LinkButton has a function that uses Response.Redirect, it somewhat clears the session or doesn't save it. I can check this since when I redirect to another page, I save the values inputted to a session first before redirecting, and validate it to the redirected page and if there's no session, bring it back to the previous page.
I have already implemented this fix to add a .browser file to my webapp but it doesn't fix my problem. I also tried this answer from SO to add a Page_PreInit and a configuration but to no avail.
My IIS Configuration has enabled for both Session and Cookies, and I honestly do not see why it will only affect Safari Browser if it is a server configuration error.
I've been working on this bug for a whole day and I can't still fix this. Please help, thanks in advance.
Update: I forgot to mention that my website is inside an iframe, after researching further I have found this question that says that Safari doesn't allow Third-Party Cookie by default. Now I can't use the said fix since my application is in ASP.NET not in PHP.
