Object no cached when TTL expires

[pablort]

Notice how Etag changes:


First and second request:
Etag    "a76-49992a41d1b5d"

Last request:
Etag    "a76-499933333a882"


Try (in vcl_fetch):

unset beresp.http.Etag;

or change Apache to use only Size and MTime to create the Etag:

FileETag MTime Size
