Java servlet how to disable caching of page

Question

How to disable caching ?

What headers should doGet set?

Could you provide a code snippet?

Here is a good article about the subject: http://www.onjava.com/pub/a/onjava/excerpt/jebp_3/index2.html — Gilberto Torrezan, Feb 14 '14 at 17:10

This will set caching to disabled on the response:

// Set standard HTTP/1.1 no-cache headers.
response.setHeader("Cache-Control", "private, no-store, no-cache, must-revalidate");

// Set standard HTTP/1.0 no-cache header.
response.setHeader("Pragma", "no-cache");

I believe you would like to add `response.setDateHeader("Expires", 0);` for proxies. See another [answer](http://stackoverflow.com/questions/3413036/http-response-caching) – mvnukov Jan 25 '13 at 11:49
Which servlet should we write this code into? the one that is redirecting to the html page keeping the cache? – Fakipo Sep 10 '22 at 00:04

I want to disabled the varnish cache if backend server return some header

eg.

if is set header like follow

JAVA code

ServletActionContext.getResponse().addHeader("ABC","true")

then in varnish if I found value of header ABC as true then I don't want to cache this page.
