Class EmptySrcAttributeCheckFilter

  • All Implemented Interfaces:

    public class EmptySrcAttributeCheckFilter
    extends Object
    implements IResponseFilter
    The EmptySrcAttributeFilter checks if an empty src attribute is found in the response. Empty src attribute is problematic as it makes some browsers, i.e. firefox, request an URL twice. Two issues arise: 1. Unnecessary server load. 2. If the browser only renders the first response, some links in the page might be broken as wicket rerendered them in the second request and dropped the ones rendered in the first request.
