Subject: Rename the vcl_fetch{} action "insert" to "deliver" as we may not
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8c84c4f141e5170f76dbc05d285a69169d03dbde;p=varnish

Rename the vcl_fetch{} action "insert" to "deliver" as we may not
insert (for instance on pass) but we certainly will deliver (unless
error or restart actions are used instead).

Update the dotgraph to 2.0 intent
