Indeed, that's one of the major use cases.

It does a bit; but the fragment identifier is unused for binary
downloads, so there's not much risk of a clash.



Just an FYI.

I've been promoting the use of fragments for (binary) video file.  (Not
here... but privately and on one public mailing list.)

For example...

http://example.com/video.mpeg#smtpe(01:20:39:15)

Also, I've suggested (privately and on one public mailing list) the use of
fragments on video files for "pointing to" clips.  (I.e., "pointing to"
intervals of the video.)

For example...

http://example.com/video.mpeg#smtpe(01:20:39:15-01:28:14:50)

(Note that there are 2 SMTPE time codes there separated with a hypen.  So it
would be the clip, with in the video, from "01:20:39:15" to "01:28:14:50".)

(This notation was inspired by the "xpointer" fragments.)


See ya

Also, "!" is currently
not legal in HTML ids, AIUI.

Indeed. In fact, it would be a security flaw to update the identifier on
redirect.
