Ramesh Narayan Jangid (Sharma)

This class can issue HTTP, not modified response for cached files.

It can check the current HTTP request to verify if it contains headers like If-None-Match or If-Modified-Since to determine if it will serve a given file or issue a 304 Not Modified HTTP status response.

The class can serve a given file as a response when it verifies that the browser does not have an up-to-date version of the specified file.

The file is served with a given Etag header value to let the browser determine the specific file version the server is sending.
