[OpenWrt-Devel] [PATCH] uhttpd2: Set HTTPS environment variable

[Dan Staples]

Currently, the only way for cgi scripts to determine if the request was made over SSL seems to be to check if the SERVER_PORT environment variable is set to 443, which is less than ideal. This sets the HTTPS environment variable, like the first version of uhttpd.
