%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.
