Varnish 4 VCL for Prestashop 1.6 (*** This is still under development, don't use it directly! ***)

default.vcl

#
# This is an example VCL file for Varnish.

# It does not do anything by default, delegating control to the
# builtin VCL. The builtin VCL is called when there is no explicit
# return statement.
#
# See the VCL chapters in the Users Guide at https://www.varnish-cache.org/docs/
# and https://www.varnish-cache.org/trac/wiki/VCLExamples for more examples.

Hello,
is this working with Prestashop 1.6.1.10?
Im trying to find good Varnish config so that the users dont get any cached content where not needed.

Thanks in advance!
