Example 3 with ServletResponse

use of org.xwiki.container.servlet.ServletResponse in project xwiki-platform by xwiki.

the class AbstractServletResourceReferenceHandler method setResponseHeaders.

/**
 * Sets the response headers needed to cache the resource permanently, if the resource can be cached.
 *
 * @param response the response
 * @param resourceReference the resource that is being served
 */

    // Cache the resource if possible.
    if (response instanceof ServletResponse && isResourceCacheable(resourceReference)) {

        httpResponse.setHeader(HttpHeaders.CACHE_CONTROL, "public");
        httpResponse.setDateHeader(HttpHeaders.EXPIRES, new Date().getTime() + CACHE_DURATION);
        // Even if the resource is cached permanently, most browsers are still sending a request if the user reloads
        // the page using F5. We send back the "Last-Modified" header in the response so that the browser will send
        // us an "If-Modified-Since" request for any subsequent call for this static resource. When this happens we
        // return a 304 to tell the browser to use its cached version.
        httpResponse.setDateHeader(HttpHeaders.LAST_MODIFIED, new Date().getTime());
    }
