This patch introduces the 'http-after-response' rules. These rules are evaluated at the end of the response analysis, just before the data forwarding, on ALL HTTP responses, the server ones but also all responses generated by HAProxy. Thanks to this ruleset, it is now possible for instance to add some headers to the responses generated by the stats applet. Following actions are supported : * allow * add-header * del-header * replace-header * replace-value * set-header * set-status * set-var * strict-mode * unset-var
