Projenizde URL ReWriting yaparken Css 'in çalışmadığı zamanlar olabiliyor,

Çözüm yollarını aşağıda bulunmakta.

1- CSS dosyasınızın başına "/" koyacaksınız, örneğin:
<link href="/style.css" rel="stylesheet" type="text/css" />

2- CSS dosyanızın adresini direkt yazacaksınız, örneğin:
<link href="http://www.zekiakdogan.net/style.css" rel="stylesheet" type="text/css" />

3-Meta tagı olarak aşağıdaki kodu ekleyin, örneğin:

//Şuanki zamanı alıyoruz
DateTime serverTime = DateTime.Now;
//UTC yani greenwich teki zaman hesapliyoruz
DateTime utcTime = dT.ToUniversalTime();
//Trkiye icin 2 saat farki ekliyoruz
DateTime turkeyTime = utcTime.AddHours(2);
