SYNOPSIS

import condhdr;

condhdr.set(<string to test>,<regexp for test>,<header field name>,<header field value>)

DESCRIPTION

Implements conditionnal (regexp driven) setting of http header field and value. Useful when Varnish is used to set the Cache-Control headers in that case you would have many :

if (bereq.url ~ "/^/path/*.html"){

beresp.http.Cache-Control="max-age=30s";

}

it allows more compact configuration file If more than one condhdr.set is matched by string, the last one overrides the others
