<ul></ul><p>I find the etag returned in Swift on DLO objects are also some 'fake' stuff.</p>
<p>The response’s ETag for a GET or HEAD on the manifest file will be the MD5 sum of the concatenated string of ETags for each of the segments in the manifest (for DLO, from the listing <container>/<pre>). Usually in Swift the ETag is the MD5 sum of the contents of the object, and that holds true for each segment independently. But it’s not meaningful to generate such an ETag for the manifest itself so this method was chosen to at least offer change detection.
