## Workaround openstack nova+openvswitch mtu issues when no jumbo frames are available,
## by setting up udev at neutron-gateway to hook on routing interface creation to
## lower the MTU (thus trigger ICMPs for PMTU discovery)
## See: https://blueprints.launchpad.net/neutron/+spec/network-options-mtu
## keywords: openstack, nova, openvswitch, mtu, 1500, no jumbo frames
## Create these two files:

varnish vcl for ghost blogging platform
#
# Varnish VCL file for Ghost blogging platform.
# http://ghost.org/
#
# Written for Ghost v0.3.0.
#
# This is a low-hanging-fruit type of VCL. TTL of objects are overridden to 2
# minutes, and everything below /ghost/ is pass()-ed so the user sessions
# work.
