In Azure all hosted sites have URL Rewrite and ARR (Application Request Routing) modules installed but the proxy functionality is disabled by default in ARR. So, when you create a simple rewrite rule like the one that follows:

Notes

ServiceStack has recently announced that will go commercial from version 4 and on. Although it is a very useful library that worth paying for you might not want to go straight ahead to acquire a license. One option is to downgrade to version 3.9.71 which is free to use and decide later if you want to buy a license or find a better alternative. In…

When you want to completely delete a directory and it has files with long names in it you can use ROBOCOPY Let’s assume you want to delete a folder under the name dir_to_delete from a command line you can do the following:
