Clojurians Log v2

Hi, I am serving resources such as css or js as follows:

(y.resources-resource/new-resources-resource "public/css/")
     (y.resources-resource/new-resources-resource "public/js/")

@pavel.klavik if you curl the file, does it send a last modified? is that last modified changing when you change the file?

ya, the modified version is correctly send

I don't know why your browser is ignoring the last modified

If you go into the network tab, maybe you can check what curl it is doing

Ok, so the problem is unrelated to yada. I will have to learn how browser caches work in more detail.

Yada might be broken :) or maybe a combination of both

when I update the css file, the yada response have last modified field updated

Maybe yada should also send max-age or similar.

Chrome is infamous for an aggressive caching policy, firefox doesn't have this issue iirc.

I don't see it anywhere in the headers

HTTP/1.1 200 OK X-Frame-Options: SAMEORIGIN X-XSS-Protection: 1; mode=block X-Content-Type-Options: nosniff Content-Type: text/css;charset=utf-8 Last-Modified: Wed, 13 Mar 2019 20:07:38 GMT Server: Aleph/0.4.4 Connection: Keep-Alive Date: Wed, 13 Mar 2019 20:29:44 GMT transfer-encoding: chunked

https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Cache-Control cache-control max-age=0 might tell chrome to send if-last-modified requests, that's the ultimate goal here.

https://stackoverflow.com/questions/11245767/is-chrome-ignoring-cache-control-max-age might be relevant though

so yada should return that as part of the response?

maybe. I'm not sure of enough detail about how chrome/firefox/etc. behave I'm afraid.

what is the easiest way to add max-age in yada?

fork it, do an install, or copy the code into your project and try modifying it until it does what you expect. I think a PR to fix this would be very welcome.

although, for me, the goal is that the cache is used when the file hasn't changed.
