Hi,
When apache or tomcat serves static files, they add "Last-Modified" but no
Expires nor Cache-Control.
In that cas browsers are using heuristics to know how long the file must be
cached.
(

)
Workaround for apache >= 2.4 : globally add the following on all apaches:
Header setifempty Cache-Control "max-age=86400" "expr=-n resp('Last-Modified') &&
-z resp('Expires')"
Anyway, AFAIK best solution for CAS is to use themes and versionize theme name
(cache busting).

Don’t recall seeing cache-control in CAS itself (doesn’t mean it’s not there).
We've been doing the following in httpd:
<LocationMatch"\.(css|gif|jpg|png|js)$">
<IfModulemod_expires.c>
ExpiresActiveOn
ExpiresByTypetext/css "access plus 1 hour"
ExpiresByTypeimage/gif "access plus 1 hour"
ExpiresByTypeimage/jpeg "access plus 1 hour"
ExpiresByTypeimage/png "access plus 1 hour"
ExpiresByTypetext/javascript "access plus 1 hour"
ExpiresByTypeapplication/javascript "access plus 1 hour"
</IfModule>
</LocationMatch>

Hi:
Trying to install a custom login page I noticed this strange behaviour with an
apache front-end of cas 4.0.1.
Here is my Cas properties file:
src/main/resources/cas-theme-default.properties:
#standard.custom.css.file=/css/cas.css
standard.custom.css.file=/css/mydomain.css
cas.javascript.file=/js/cas.js
This new css is loaded only with a refresh of the browser.
Is there any issue regarding this behaviour?
Thanks!
Manfredo
