I thought that myself, and have tried purging with the specific header being called - still no luck.
Doesn't a purge by default, remove all variants of the specified URL? :) From: Jennings, Raymond [mailto:[email protected]] Sent: Friday, 7 March 2014 10:06 AM To: Paul McInerney Cc: [email protected] Subject: Re: varnish 3.0 + mobile app I assume your purge is not hashing properly. When you purge it has to match whatever it hashed on when the obj went into the cache. I have problems using the standard sub vcl_hash so I hash only on the URL and not the hostname so this let's me purge from outside of the "restricted area." In your case I think you probably need to purge all possibilities based on that X-header you are setting. If that gets too difficult I fallback on doing a BAN instead.

When the app hits the varnish frontend, it has the user-agent string set as 'mobileapp'. So I have put in place a subroutine that correctly identifies the app and sets a custom x-device header to send to the backend for rendering the page(s) in the required format. This part is working well with the same URL now serving both formats of the page, however when I issue a purge against the URL, it purges the cached versions of the PC version of the page, and doesn't clear all variants (which should include the mobileapp version afaik ) Here's the subroutine called from vlc_recv sub identify_device { unset req.http.X-UA-Device; set req.http.X-UA-Device = "pc"; if (req.http.User-Agent ~ "mobileapp" ) { set req.http.X-UA-Device = "mobileapp"; } } and the hash being set based on device sub vcl_hash { if (req.http.X-UA-Device) { hash_data(req.http.X-UA-Device); } } What am I doing wrong? or missing? or not understanding?
