---

[OmniFaces utilities] The getDefaultResourceMaxAge() method returns the default resource maximum age in milliseconds.

---

Method:

See also: Faces#getInitParameter()

Usage:

import org.omnifaces.util.Hacks;

...

// e.g. 604800000 milliseconds

long maxAge = Hacks.getDefaultResourceMaxAge();

OmniFaces uses this method to set the Expires response header in org.omnifaces.resourcehandler.DynamicResource:

@Override

public Map<String, String> getResponseHeaders() {

 Map<String, String> responseHeaders = new HashMap<>(RESPONSE_HEADERS_SIZE);

 responseHeaders.put("Last-Modified", formatRFC1123(new Date(getLastModified())));

 responseHeaders.put("Expires", formatRFC1123(new Date(System.currentTimeMillis() + Hacks.getDefaultResourceMaxAge())));

 responseHeaders.put("Etag", String.format("W/\"%d-%d\"", getResourceName().hashCode(), getLastModified()));

 responseHeaders.put("Pragma", ""); // Explicitly set empty pragma to prevent some containers from setting it.

 return responseHeaders;

}
