return (lookup) means

[nick tailor]

Hi  dhanushka,

Usually, all image files are static and you can just have varnish always
cache them. The objects cached. you can have it set so that the cache is
updated say every 30 seconds as long as your webservers are up, and you can
also set, should your webservers go down the ttl for the objects cached is
now longer making everything appear that its all still up, you fix your
issues with your backend. The better you know your application and how it
works, the more fine tuned you can make your VCL

Cheers
