The one limitation that exists is that the client requesting the new content will be kept waiting. While that client is waiting all the others will get the new content. You can have a look at "man vcl" or the varnish tutorial ( https://www.varnish-cache.org/docs/trunk/tutorial/handling_misbehaving_servers.html) for some docs on how to do it. If you find any of the docs unclear, please let me know. -- Per Buer, CEO Phone: +47 21 98 92 61 / Mobile: +47 958 39 117 / Skype: per.buer *Varnish makes websites fly!* Whitepapers <http://www.varnish-software.com/whitepapers> | Video<http://www.youtube.com/watch?v=x7t2Sp174eI> | Twitter <https://twitter.com/varnishsoftware>
