Some redirects return `302` when they should probably return `301`

In my excavations of the CantusDB logs, I discovered that responses to some requests that I think are permanent redirect are actually returning 302 responses.

In particular, /node/<id> and /office return 302's rather than 301's. My understanding is that both of these redirects are permanent for the purpose of harmonizing Old and NewCantus URLs.

And 301 indicates a permanent redirect, correct?

We should be a bit careful - in something relating to DataLake earlier today, we were talking about renaming, say, /sources to /source. We've already switched /genre to redirect to /genres, so we should be careful not to swap things back and forth.

Redirects that should be permanent, I think:

• sites/default/files/csv/<str:source_id>.csv -> source/<str:source_id>/csv/
• node/<int:pk> -> source, chant, sequence, etc. detail page
• indexer/<int:pk> -> the relevant user page
• sites/default/files/documents/1. Quick Guide to Liturgy.pdf, sites/default/files/documents/2. Volpiano Protocols.pdf, ..., sites/default/files/HOW TO - manuscript descriptions-Nov6-20.pdf -> the relevant static files

some which we may not be certain about:

• /genre -> /genres (but maybe this one is properly permanent?)
• /office -> /offices (ditto)
• (somehow, /feasts has always been /feasts...)

And 301 indicates a permanent redirect, correct?

Yes

Looks like this will be trivial to implement once we're very confident of our list of permanent redirects. return redirect(reverse("csv-export", args=[source_id])) becomes return redirect(reverse("csv-export", args=[source_id]), permanent=True)

Going to make an executive decision and say we're currently happy with all of our redirects, and that we should communicate that they are permanent. This will just require someone going through all the redirects in our views and adding a permanent=True kwarg.
