   Hi! Your browser is caching the file. This is out caching policy for files:

   Cache-Control: "max-age=60, s-maxage=%0.f, must-revalidate"

   pico/pkg/apps/pgs/web_asset_handler.go

   Line 280 in 4902f05

   "max-age=60, s-maxage=%0.f, must-revalidate",

   Hi! Thanks for the quick response! Not the case... Not client-side caching...

   • I had trouble with one updated html file refreshing. Cleared client and server cache. No joy after 15 min-ish (was expecting instant).
   • deleted the project and cleared server cache. I could confirm (sshfs) that the project was gone.
   • cleared cache in my browser (Firefox). No joy.
   • ran a fresh different browser (Chromium) that had never seen the site. Same.
   • curl (never caches on the client side) was returning ghost pages more than 30 min after I deleted the project + cleared the cache (ssh pgs.sh rm my-project --write then ssh pgs.sh my-project cache --write). The screenshot shows the long gone 404.html.
   • I tried now (about 2h later) and it says project not found which is a good result 😃
   • Not sure you have logs that may be helpful with my whole session history? tofinopickleball

   Opinion:

   • You have a timing issue for the propagation of project deletion and clearing the server cache.
   • May be related to the size of the project -- ~60MiB ~600 files.
   • I had a test project earlier (10 times smaller-ish) did not seem instant but was a lot more snappy.

   Let me know if I can help in any way. BTW: I love ❤️ pico.sh + would really like you guys to be successful with it.

   Thanks for the report. I'll look into this. Could you upload the site to a temporary project and share it with me? I'll use that to test.

   Update: traced it down to the "vanity URL" project. Repro:

   1. Create a new pgs.sh project (tmp). Drop a file ('hello.txt`) in it.
   2. Link the "vanity URL" to this project.
   3. File shows up ok in the tmp project and in the vanity URL. Nice! 😎
   4. Change the contents of hello.txt
      • The tmp project shows the modified file ✔️
      • The vanity URL shows the cached file 🤔 . Clearing cache doesn't help.
      • Accessing the "vanity" linked project as {user}-{project}.pgs.sh shows the modified file ✔️

   Ahh, nice catch! I bet our cache-key is not right for vanity domains. Will work on this asap.
