Hello, is there a rewrite method in Varnish which has same effect like following rule in Apache 2.4? RewriteRule ^/(.*)$ http://plone:8080/VirtualHostBase/https/plone.example.net:443/cms/VirtualHostRoot/$1 [L,P,E=remoteUser:%{LA-U:SSL_CLIENT_S_DN_CN}] This rule reads CN from a client certificate and set remoteUser to CN. best regards Christian
