RE: Purge and cache content mist.
Thank You DES for your answer. About the url.purge, do I purge an URL or an URI with it ? Does url.purge firstdomain\.com/that-part/.* will do the job for all contents under /that-part/ of domain firstdomain.com ?

It almost sounds like we can't be bothered to implement it. The real reason is that URLs are not stored in the cache - hash strings are. What's more, different URLs may hash to the same object, so there would be no way to generate an unambiguous list. That being said, the FAQ is correct in that it would be a very expensive operation - listing the contents of the cache on a large server could very well stall it for seconds or, in the worst case, minutes.

hi Am Montag, 23. März 2009 15:10:01 schrieb Sébastien FOUTREL: Thank you. About the url.purge, should I understand that url.purge doesn't manage hosts so url.purge /that-part/.* will purge http://onedomain.com/that-part/* and http://otherdomain.com/that-part/* ? Can I use onedomaine\.com/that-part/.* to purge only '/that-part/' in that host :) ? on my setup i only have one host. i'm sure you can restrict that to one single host, but i don't know by heart. if url.purge can't do that you can setup url purging see the link below the faq question http://varnish.projects.linpro.no/wiki/FAQ#HowcanIforcearefreshonaobjectcachedbyvarnish http://varnish.projects.linpro.no/wiki/VCLExamplePurging regards, harald -Message d'origine- De : Harald Friessnegger [mailto:har...@webmeisterei.com] Envoyé : lundi 23 mars 2009 14:14 À : varnish-misc@projects.linpro.no Cc : Sébastien FOUTREL Objet : Re: Purge and cache content mist. hi sebastien Am Montag, 23.

Re: Purge and cache content mist.
on my setup i only have one host. i'm sure you can restrict that to one single host, but i don't know by heart. I don't think you can. At least I couldn't find any method to do host based purging without using the PURGE HTTP Method. if url.purge can't do that you can setup url purging see the link below the faq question http://varnish.projects.linpro.no/wiki/FAQ#HowcanIforcearefreshonaobjectcached byvarnish http://varnish.projects.linpro.no/wiki/VCLExamplePurging True, but if he's doing this he can't do Wildcard purging! If there's any way to do wildcard purging on a specific hostname I'd be interested in that too. Something like for instance PURGE /foo/bar/.* HTTP/1.1 Host: some.host.tld But afaik this is not possible yet.
