HTTP -- get HTTP headers

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

Parameters

Name Description
"name" Name of the header to get
