I've asked this here but I'll try here also
I am running behind a CDN that turns my https request into http and sets X-Forwarded-Proto.
I know in nginx I can create a rule that rewrites my request as
localhost:8080/VirtualRequestBase/https/realsite.com:80/VirtualHostRoot/siteroot so that urls come out right.
However I have a zope setup where I keep many sites and I don't want to have to change the nginx config every time I add a new one. I normally use the VHM mappings tab to map domains to siteroots, however it will ignore the VirtualHostBase directive in the path. In addition you can mix the two styles of VHM, ie set
localhost:8080/VirtualRequestBase/https/realsite.com:80 and expect it use the mappings.
