Synopsis

$h->scan($sub)

Invokes the subroutine referenced by $ sub for each header field in the object. The subroutine is passed the name of the header and its value as a pair of arguments. For header fields with more than one value, the subroutine will be called once for each value.

The HTTP::Headers class allows you to use a number of convenience methods on header objects to set (or read) common field values. If you supply a value for an argument, that value will be set for the field. The previous value for the header is always returned. The following methods are available:

date
expires
if_modified_since
if_unmodified_since
last_modified
content_type
content_encoding
content_length
content_language
title
user_agent
server
from
referrer
www_authenticate
proxy_authenticate
authorization
proxy_authorization
authorization_basic
proxy_authorization_basic
