I\'m trying to set a \".svg\" image as background-image using css, but it is not working. The url is valid and returns 200 status code and works on \".png\" images.
In my case, I included all of the mime-types I wanted in the applicationHost.config file (which is usually located at C:\Windows\System32\inetsrv\config) under the scope, like Joachim Isaksson mentioned. This allows all of my IIS sites to inherit the same mime-types, and gives you one location to change them if something goes wrong.
