This is not really a bug per se.

What happens is that we generate a weak ETag when the request is too close to the modification
time of the file (as dictated by RFC 2616, ETags should have 60-second resolutions).  After
that second has elasped and the file hasn't changed, that weak entity tag would be made strong.
 Creating a weak tag in mod_dav_fs isn't always desirable since it isn't keyed to a request
- therefore all of its entity tags should be strong rather than weak.

However, RFC 2616 explicitly calls out strong entity comparison and weak entity comparison
functions.  Currently, mod_dav only uses strong entity comparison.  So, I modified mod_dav
to do weak entity comparison instead.

See modules/dav/main/util.c r1.45.

This has been proposed for the next stable release of httpd-2.0.

Thanks for using Apache!
