I am starting on web-security and I have to control the cache on the portal, this portal has many urls. I understand that I need to set the header with this:

  response.setHeader("Cache-Control","no-cache,no-store,must-revalidate");
  response.setHeader("Pragma", "no-cache");

But my question is: The code above is valid for all the urls that I want to controling (You know the cache) or how I set this attribute for all the urls or for a url in specific?.

  • Hi Yohannes Gebremariam: I meant the urls belong to the main portal, ie the main url is [example.com] and the "other" urls are [example.com/another_url] and [example.com/this_is_another_url] and I want to control the cache of the 3 urls above. how can I control the cache for all of them?, thanks in advance – Rock Pz Jun 05 '18 at 21:19

Put this code in a web filter and map the filter to all the urls where you want to disable caching.

Assuming you have access to both request and response objects. You can use one of the following methods of HttpRequest object in your control method to set those response parameters

 - getPathInfo()
 - getRequestURL()
 - getRequestURI()

I mean something like this

if(request.getRequestURL().equals("http://someurl"))
{
//do your stuff
}
