switch http to https if header contains "SSL" =1

I'm using the editor with this code and I can't save it, the editor list errors in invalid arguments and missing {[}.

 

 

I need the code on the HTTP VS to redirect back to HTTP when someone adds items to their cart after checking out they will redirect back to HTTP.

 

 

We have code that does this on the server side but then we need to have ssl on client and server side.

 

 

Are current setup we would require 2 Separate VS's and POOLS and 5 Node per website for 400+ sites.
