HTTPS -- get HTTPS headers

The same as %HTTP% but operates on the HTTPS environment variables present when the SSL protocol is in effect. Can be used to determine whether SSL is turned on.

• Called with the name of an HTTP request header field, returns its value. Capitalization and the use of hyphens versus underscores are not significant.
• Request headers are sent by the browser to the server. It is not possible to access the Response headers returned to the browser.
• Only returns headers permitted by site configuration.
• When called without a parameter, nothing is returned. See VarHTTPS for other options.
