For the problem statement/goals, see dandi/dandiarchive#427.

I am no vue anything (not even a novice) so may be this is a wrong direction: Quick search lead me to https://stackoverflow.com/questions/34623833/how-to-remove-hashbang-from-url which in turn to https://router.vuejs.org/guide/essentials/history-mode.html#example-server-configurations which suggests that there is a "history" mode which would make it possible to make URLs look normal (without placing all args into a fragment).

with switching away from using hash (fragment) mode in web ui we would be able to place dandiarchive.org behind reverse proxy (#427) to provide any necessary consistent mapping from permalinks to web ui and/or API end points without redirects.
