I am trying to run many HTTP and HTTPS website behind a Squid Reverse Proxy. But it is not acceptable to run the site in HTTPS only, so I need to redirect to HTTPS on occasion. But my backend web server does not know the request was made in HTTPS due to the reverse proxy. I need to be able to add a custom header the the request as it passes through the reverse proxy. I want to add X-FORWARDED-SSL header to each request that came in as HTTPS before it is forwarded to the correct webserver. I have seen some discussion about header_replace but that doesn't seem appropriate as I need to ADD the header, but only if the request came in as HTTPS. Could someone please help me with how the squid.conf file should be crafted to do this? Or is it not possible?
