Resources first checked against server not retrieved from cache right away

Resources that are in ui:insert's,ui:include's are not cached. While the other stuff that is defined in my template is. The resources that are accessed in the ui:'s do have the right "Expires"-header, but they also have Cache-Control:no-cache & Pragma:No-cache. The other resources that are not accessed in the ui:insert and ui:include don't have this, like the stylesheets and js in the header. Now and then some random resources in the ui:'s do get from the cache, like 2 out of 12. And those 12 images are defined exactly the same way, I don't get why those 2 would get cached.

I have tried everything I can, and can't figure it out. (Mojarra 2.2.12 is used)

The param javax.faces.PROJECT_STAGE has the value Production and the param com.sun.faces.defaultResourceMaxAge has 604800000.

Example of my main_pages_template, is use this template at various pages with the template-attribute in the ui:composition.

<html lang="#{localeBean.language}"
  xmlns="http://www.w3.org/1999/xhtml"
  xmlns:ui="http://xmlns.jcp.org/jsf/facelets"

        <title><ui:insert name="title">Facelets Template</ui:insert></title>

        <ui:include src="/WEB-INF/templates/favicon.xhtml" />

    </h:head>

    <h:body id="secure">

        <div id="wrapper">
            <div id="top">
                <ui:include src="/WEB-INF/templates/header_template.xhtml" />
            </div>

            <div id="content" class="center_content">            
                <ui:insert name="content">Content</ui:insert>
            </div>

            <div id="footer">            
                <ui:include src="/WEB-INF/templates/footer_template.xhtml" />
            </div>
        </div>

    </h:body>
</f:view>

Solution

  • I figured out that the server was responding with Cache-Control: no-cache and Pragma: no-cache because the resources were accessed on a secure page that was defined by a GlassFish Security Realm (j_security_check).

    To solve this I implementend the solution here: Static resources are not cached referenced from glassfish secure page

    I added <property name="securePagesWithPragma" value="false" /> as a property from glassfish-web-app in the glassfish-web.xml. Now only the Cache-Control header is set with the value, private which is fine. Private means that only the end user can cache it and not inbetween proxies.
