Here’s a weird one. I thought I would start to use https://docs.racket-lang.org/frog/index.html\|Frog . The command raco frog -bp builds my site, and opens <http://localhost:3000/index.html> in a browser. Up until about an hour ago, that worked — it correctly displayed index.html . But now instead it shows “Welcome to the Racket Web Server”. What’s really weird, is: (a) this only happens in Firefox. When I copy-and-paste the URL to Safari or Chrome (or curl), I see the correct index.html . (b) the URL <http://localhost:3000/> (without the filename) shows the index page in Firefox. I’m basically planning to ignore the issue, but if anyone has any insight, I’d be very grateful to hear it.

Cache issue?

Well … huh. Yes. Yes, it was.
