I had to look into this recently myself. Take a look at the documentation on how gzip/deflate are handled. For one object varnish can potentially have multiple objects: gzipped, deflated and uncompressed.

Our backend servers are not adding any 'Vary:' header to responses, but objects > object_heads by a great difference. The ratio objects:object_heads is ~ 2:1. The vcl is clean and simple: sub vcl_recv { unset req.http.cookie; if (req.request == "HEAD") { return(pass); } } Is there anything besides 'Vary' that makes varnish cache multiple objects ? What else could be causing this ? _______________________________________________ varnish-misc mailing list [email protected] http://lists.varnish-cache.org/mailman/listinfo/varnish-misc _______________________________________________ varnish-misc mailing list [email protected] http://lists.varnish-cache.org/mailman/listinfo/varnish-misc
