Disable Browser Caching

https://bedigit.com/blog/disable-browser-caching/

The correct minimum set of headers that works across the most important browsers:

Cache-Control: no-cache, no-store, must-revalidate
Pragma: no-cache
Expires: 0

Where:

Cache-Control is for HTTP 1.1
Pragma is for HTTP 1.0
Expires is for proxies

For the Web Pages (HTML) add the following tags to the page(s) you want to keep browsers from caching (the code must be in the section of your page, for example right after tag):</p> <pre><code><meta http-equiv="Cache-Control" content="no-cache, no-store, must-revalidate" /> <meta http-equiv="Pragma" content="no-cache" /> <meta http-equiv="Expires" content="0" /></code></pre> <p>.htaccess (Apache)</p> <pre><code><IfModule mod_headers.c> Header set Cache-Control "no-cache, no-store, must-revalidate" Header set Pragma "no-cache" Header set Expires 0 </IfModule></code></pre> <p>PHP</p> <pre><code>header('Cache-Control: no-cache, no-store, must-revalidate'); header('Pragma: no-cache'); header('Expires: 0');</code></pre> <p>Java Servlet</p> <pre><code>response.setHeader("Cache-Control", "no-cache, no-store, must-revalidate"); response.setHeader("Pragma", "no-cache"); response.setDateHeader("Expires", 0);</code></pre> <p>ASP</p> <pre><code>Response.addHeader "Cache-Control", "no-cache, no-store, must-revalidate" Response.addHeader "Pragma", "no-cache" Response.addHeader "Expires", "0"</code></pre> <p>ASP.NET</p> <pre><code>Response.AppendHeader("Cache-Control", "no-cache, no-store, must-revalidate"); Response.AppendHeader("Pragma", "no-cache"); Response.AppendHeader("Expires", "0");</code></pre> <p>Ruby on Rails</p> <pre><code>response.headers['Cache-Control'] = 'no-cache, no-store, must-revalidate' response.headers['Pragma'] = 'no-cache' response.headers['Expires'] = '0'</code></pre> <p>Python on Flask</p> <pre><code>resp.headers["Cache-Control"] = "no-cache, no-store, must-revalidate" resp.headers["Pragma"] = "no-cache" resp.headers["Expires"] = "0"</code></pre> <p>Google Go</p> <pre><code>responseWriter.Header().Set("Cache-Control", "no-cache, no-store, must-revalidate") responseWriter.Header().Set("Pragma", "no-cache") responseWriter.Header().Set("Expires", "0")</code></pre> <p>Resources</p> <pre><code>http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.9 http://stackoverflow.com/a/2068407</code></pre> </div> </div> <div class="comment"> <div class="user"> <a rel="noreferrer nofollow" target="_blank" href="https://github.com/uniquejava"><img src="https://avatars.githubusercontent.com/u/1049271?v=4" />uniquejava</a> commented <strong> 5 years ago</strong> </div> <div class="markdown-body"> <h2>no-cache 和 no-store的区别</h2> <p><a href="https://stackoverflow.com/questions/7573354/what-is-the-difference-between-no-cache-and-no-store-in-cache-control">https://stackoverflow.com/questions/7573354/what-is-the-difference-between-no-cache-and-no-store-in-cache-control</a></p> </div> </div> <div class="comment"> <div class="user"> <a rel="noreferrer nofollow" target="_blank" href="https://github.com/uniquejava"><img src="https://avatars.githubusercontent.com/u/1049271?v=4" />uniquejava</a> commented <strong> 5 years ago</strong> </div> <div class="markdown-body"> <h2>HTTP Caching</h2> <p><a href="https://developers.google.com/web/fundamentals/performance/optimizing-content-efficiency/http-caching">https://developers.google.com/web/fundamentals/performance/optimizing-content-efficiency/http-caching</a></p> <h2>Spring 作用于Controller</h2> <pre><code class="language-java">public class ReqInterceptor implements HandlerInterceptor { @Override public boolean preHandle(HttpServletRequest req, HttpServletResponse res, Object handler) throws Exception { res.setHeader(HttpHeaders.CACHE_CONTROL, "no-cache, no-store, must-revalidate");
