[keycloak-dev] Themes: Browser cache not used for static resources (img, css, js)

[jo0815]

Hello Stian,

thanks for your quick response.
Your're right. The cache-controll-Header is set with the configured
theme/staticMaxAge (CacheControlUtil.java).

I was confused since reloading (pressing F5) triggers bypassing the
cache, which is described (for Chrome) here:
https://stackoverflow.com/questions/11245767/is-chrome-ignoring-cache-control-max-age
<https://deref-gmx.net/mail/client/5rKf3nAN78g/dereferrer/?redirectUrl=https%3A%2F%2Fstackoverflow.com%2Fquestions%2F11245767%2Fis-chrome-ignoring-cache-control-max-age>

But selecting the location bar and hitting 'enter' shows the desired
behaviour: The local browser cache is used.


Thanks
Jonathan Strampp
