A DNN Theme footer include file that outputs useful Debug info for OHS, development, etc. C#, CSharp, .NET

__debug.ascx

<%-- THIS IS THE C# CSharp .NET VERSION
NOTES: 
 - the way we get the Skin name is "janky" ;)
 - uses Bootstrap (next version won't?)

How to use:
1. Save this file in your theme folder, usually includes/__debug.ascx
2. Update the IPs; add the WAN IP(s) for your location(s)
3. Update the Bootstrap version manually
4. Either in includes/_footer.ascx (or Home.ascx), before closing DIV in main <footer> section add this
<!-- #include virtual="__debug.ascx" --> 
5. To view the output when NOT at an allowed IP, just add /debug/on to your URL

FUTURE: no Bootstrap
