ModifyHeaderHandler < Codev

modifyHeaderHandler( \%headers, $query )

\%headers - reference to a hash of existing header values
$query - reference to CGI query object

Lets the plugin modify the HTTP headers that will be emitted when a page is written to the browser. \%headers= will contain the headers proposed by the core, plus any modifications made by other plugins that also implement this method that come earlier in the plugins list.

$headers->{expires} = '+1h';

Note that this is the HTTP header which is not the same as the HTML <HEAD> tag. The contents of the <HEAD> tag may be manipulated using the TWiki::Func::addToHEAD method.

Since: TWiki::Plugins::VERSION 1.026
