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.
ALERT! The HTTP and HTTPS macros are deprecated as of Foswiki release 2.1. and will be removed in a future release.

Parameters

Parameter Description Default
"name" Name of the header to get optional
