Actually I realize now that ring.middleware.not-modified
doesn't actually add the header itself. That's handled elsewhere such as in ring.util.response/file-response
.
I'd be fine with adding that. Perhaps we could even use the middleware directly in this project? PR welcome, if you get to it earlier than I do.
I can contribute a PR here if desired. Just want to document the bug first.
Description:
babashka.http-server
is used with Live.js to hot-reload changes to HTML, CSS, and JS. It usesHEAD
requests to check the following headers:Etag
,Last-Modified
,Content-Length
, andContent-Type
.Problem:
babashka.http-server
doesn't returnLast-Modified
headers in the HTTP response. This means Live.js will fall back to usingContent-Length
to determine if there are new changes. It's possible for this to cause missed reloads since some changes (such as changing an integer in CSS) will result in the sameContent-Length
even though the content has changed.When I use
python3 -m http.server
to serve the same files, I don't miss any changes even if the output file length is the same.Solution: Use
ring.middleware.not-modified
or something similar to add theLast-Modified
to the HTTP responses.
