 Hi,

 this is how I start varnishd:

 -a 0.0.0.0:8080 -f /etc/varnish/default.net.vcl -t 120s -s
 file,/var/lib/varnish/varnish_storage.bin,1g

 The caching works but I cant purge any files (VCL config is attached).

 I cant use 1.1 since for some reason I never get a cache_miss ... it
 always return he same file (the first file it served after the varnishd
 restart).

Comment:

 You should not put the host part in the PURGE command, try this instead:

 {{{ PURGE /users/7238558.jpg }}}
