Hi,
The result of createRss.getTimestamp_long() is date in long format of last modification of my feed in RSS. This is the date when new message has been registered.
I try to display 303 error when there is no changes.
Please have a look for my present code. I know that there is here something wrong.
System.out.println("Last modification is "+createRss.getTimestamp_long());
response.setDateHeader("Last-Modified", createRss.getTimestamp_long());
long lastModifiedRequest = request.getDateHeader("If-Modified-Since");
if(createRss.getTimestamp_long()>lastModifiedRequest){
System.out.println("There is new message");
}else{
System.out.println("There is NO new message");
response.setStatus(HttpServletResponse.SC_NOT_MODIFIED); // 304
}

Hi,
Yes. Now it works. But I have the other small problem.
In my servlet I want to send date of last modification and when I refresh the browser to get back this date.
In response I try to send the date and in request to get this date.
Unfortunately in response I get -1
Please look for following code:
response.setDateHeader("Last-Modified", createRss.getTimestamp_long());
request.getDateHeader("Last-Modified");
long lastModifiedRequest = request.getDateHeader("Last-Modified");
System.out.println("Last modification has been done on " + lastModifiedRequest);
Can you help.
Regards,
Rafal
