2. اگر آدرس درخواستی شامل کوئری باشد صفحه کش نخواهد شد:    http://www.site.info/postarchive.htm?id=25 
3. برای پاسخ ازمکانیزم‌های فشرده سازی پویا استفاده شده باشد مثل gzip کش نخواهد شد
4. صفحه درخواست شده صفحه اصلی سایت باشد کش نخواهد شد :   http://www.dotnettip.info ولی اگر درخواست بدین صورت باشه http://www.domain.com/default.htm  کش خواهد کرد.
5. درخواست به صورت ناشناس anonymous نباشد  و نیاز به authentication داشته باشد کش نخواهد شد (یعنی در هدر شامل گزینه authorization می‌باشد).
6. درخواست باید از نوع نسخه http1 به بعد باشد.
7. اگر درخواست شامل Entity-body باشد کش نخواهد کرد.
8. درخواست شامل If-Range/Range header باشد کش نمی‌شود.
9. کل حجم response بییشتر از اندازه تعیین شده باشد کش نخواهد گردید، این اندازه در کلید ریجستری UriMaxUriBytes قرار دارد. اطلاعات بیشتر
10. اندازه هدر بیشتر از اندازه تعیین شده باشد که عموما اندازه تعیین شده یک کیلو بایت است.
11. کش پر باشد، کش انجام نخواهد گرفت.
