that is a bug. in ATS, a missed range request must be passed to the origin server, and not saved because the data is incomplete.
if it is with V4.1.2 or master version, that is a new bug. if not, that may be a fixed bug, it is known to broken in 3.2-3.3 releases. if you can confirm that master tree have this issue, please file the bug in the jira. thanks 在 2013年12月12日，下午8:43，Jan-Frode Myklebust <[email protected]> 写道： > When sending an If-Modified-Since for an object that's not cached in > ATS, it doesn't seem like the IMS is propagated to the backend server, > so we're always getting 200/OK and full document sent to the client.
