How to configure the HTTP Cache-Control for static files?

[optech]

Hi,

I'm new with JBoss/Wildfly, could be a stupid question, but I've searched in web, but still no answer...

I have a project, ServerSide is JEE & Wildfly (src/java/) and front end is html + javascript (src/webapp/),

I would like to configure the HTTP Header's Cache-Control for static files like html file,

like ETAG or maxAge, to avoid Refresh everywhere after a new version..

I know in Java I can add Cache-Control to Response's header, but it seems that

they only work for Request to Java, but not for static files.

How can I configure this for them? or simply in global?

I've also tried to insert Filter in subsystem for undertow:

  <response-header name="Cache-Control" header-name="Cache-Control" header-value="no-cache"/>

then inserted a the following for default-host in <server>

  <filter-ref name="Cache-Control"/>

but it also only works for dynamic part....

Thanks in advance!

Where is your static content? in deployment?

Hi Tomaz,

yes they are in the war file (deployment)...

Sorry, I found the problem.

Before I configure the standalone.xml, I've tried a Java Class AccessControlInterceptor,

which implements ContainerResponseFilter, the method filter() was overridden with:

   responseContext.getHeaders().add("Cache-Control", "no-cache");

it works only for the Java parts, but not for direct static files. After the I tried the configurations.

Today, I've just delete it to clean my workspace, then I noticed alter, the config in standalone.xml for filter works for all

So the configuration directly in standalone.xml for global is correct.

Nevertheless, is it possible that I can configure the Cache-Control in Java for all (include static files)?

(so I can configure compute the checksum or give a timestamp for ETAG... )

Thank you!
