Hello all,
I am building a WebAPi with some custom .NET Authorisation filters that I am decorating on my WebAPI controller.

I need to run multiple custom Authorisation filters that need to be ensured that they are executed in a specific order. I have found a few posts around discussing how to do this:

http://www.strathweb.com/2012/06/control-the-execution-order-of-your-filters-in-asp-net-web-api/

http://stackoverflow.com/questions/21628467/order-of-execution-with-multiple-filters-in-web-api

But doing a quick search in the Umbraco code base on GitHub it seems the core is doing something with the order execution of these filters and reversing the order. I was wondering if anyone from the core team or anyone else understands why this would be done at all and more importantly if I try and implement what is suggested in the two posts I found about the order execution will I explode the Umbraco CMS internals that is going on here and totally break everything?!

Look forward to hearing back on this.

Cheers,
