Hi,

I had this problem for longer (older Keycloaks eg v19) now and im seeking help.

I have a css/custom.css which is included in my themes.properties.
Everytime I try to change the css, the css doesnt get updated.

My steps are like this:

1. build new theme with new custom.css and move to /providers
2. remove cached data manually: rm -r data/tmp/*
3. rebuild keycloak: bin/kc.sh build
4. start kc with chaches disabled for testing: bin/kc.sh start --spi-theme--static-max-age=-1 --spi-theme--cache-themes=false --spi-theme--cache-templates=false
5. delete Browser Cache

My workaround currently is to rename the css file and replace it in the themes.properties, which might be ok one or two times but I dont really want to do that.

Can anyone reproduce this problem or has a solution?

Thanks!

Update: Okay so when I deactivate caching in the browser dev tools > network analysis, the new css is loaded.
I see that the header "cache-control" is set to "no-cache"

The no-cache response directive indicates that the response can be stored in caches, but the response must be validated with the origin server before each reuse, even when the cache is disconnected from the origin server.

Currently I don't know how this validation is working, to know if it is even a keycloak issue or not

Update2: So I don't seem to have any proxy caching inbetween so I believe that it's a keycloak issue. How do you guys handle this?
