checkNotModified

public boolean checkNotModified(long lastModifiedTimestamp)

Description copied from interface: WebRequest

Check whether the request qualifies as not modified given the supplied last-modified timestamp (as determined by the application).

This will also transparently set the appropriate response headers, for both the modified case and the not-modified case.

Typical usage:

 public String myHandleMethod(WebRequest webRequest, Model model) {
   long lastModified = // application-specific calculation
   if (request.checkNotModified(lastModified)) {
     // shortcut exit - no further processing necessary
     return null;
   }
   // further request processing, actually building content
   model.addAttribute(...);
   return "myViewName";
 }

Specified by:

checkNotModified in interface WebRequest

Parameters:

lastModifiedTimestamp - the last-modified timestamp that the application determined for the underlying resource

Returns:

whether the request qualifies as not modified, allowing to abort request processing and relying on the response telling the client that the content has not been modified

Get a short description of this request, typically containing request URI and session id.

Specified by:

getDescription in interface WebRequest
