I have found out how to make to work varnish http purge plugin with Varnish 4.x in this article (funny it´s on the Varnish blog)
https://info.varnish-software.com/blog/step-step-speed-wordpress-varnish-software?success=true I have to say If I added the snippet mentioned: if (req.http.X-Purge-Method == "regex") { ban("req.url ~ " + req.url + " && req.http.host ~ " + req.http.host); return (synth(200, "Banned.")); } else { return (purge); } It didn´t work out of the box. I got the following VCL_error: - VCL_Error ban(): Expected && between conditions, found "&&" I had to change it to: if (req.http.X-Purge-Method == "regex") { ban("req.url ~ " + req.url + " && req.http.host ~ " + req.http.host); return (synth(200, "Banned.")); } else { return (purge); } So maybe for other users using Wordpress with Varnish it might be useful Regards, Miguel On 08/15/17 1:07 PM, Miguel González wrote: > On 08/11/17 12:22 PM, Dridi Boukelmoune wrote: >>> The Wordpress plugin is supposed to clean the whole cache for a website >>> when clicking on a button saying "Clear cache". >>> >>> You say from the varnishlog excerpt I sent that´s not the correct way >>> of doing so, or apparently what is logged by varnish is not a correct purge. >>> >>> So how do I tell the developer (or do it myself) to correct the code so >>> the whole cache for a given website is purged?. >> >> Use the ban() function in your VCL in this case. >> >> Dridi >> > > I currently have in default.vcl this: > > # Allow purging from ACL > if (req.method == "PURGE") { > # If not allowed then a error 405 is returned > if (!client.ip ~ purge) { > return(synth(405, "This IP is not allowed to > send PURGE requests.")); > } > # If allowed, do a cache_lookup -> vlc_hit() or vlc_miss() > return (purge); > } > > > What do I have to change to use BAN?
