This Week I Learned - Week #62

This Week I Learned:

• IIS 7.5 Express can run on Windows XP and above while IIS 8.5 Express can run on Windows Vista SP1 and above
• Compared to most other web servers and operating systems, something unique to IIS and Windows is their lack of case sensitivity when it comes to the names of paths and files. While case insensitivity may seem harmless and maybe even a little convenient, taking advantage of that flexibility (on purpose or not) can lead to unnecessary cache misses for your users. A request for the image http://asp.net/images/ui/asplogo-NEW.png is not cached if it is subsequently called via requests that don't have consistent casing - http://asp.net/images/ui/asplogo-NEW.png or http://asp.net/images/UI/asplogo-NEW.png. The IIS performance best practice is to is to pick a file casing convention and adhere to it strictly throughout your entire site.
