- 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. Returns '' if the header is not allowed.
- When called without a parameter, nothing is returned. See VarHTTPS for other options.
The HTTP and HTTPS macros are deprecated as of Foswiki release 2.1. and will be removed in a future release.
