Disable cache: how to disable the browser from caching page content

To avoid frequent interaction with the server, the browser provides the cache function. When you frequently access the synonymous JSP page, the browser will retrieve the results in the cache as a user response and does not send requests to the server. Therefore, it is often unable to reflect the latest processing results of the server.

 

 

If a JSP or servlet program does not require the client browser to cache its corresponding content, you can add the following code:

Response. setheader ("Pragma", "No-Cache"); response. setheader ("cache-control", "No-Cache"); response. setdateheader ("expires",-10 );

 

 

Conclusion: disabling the browser to cache JSP or servlet Response Results ensures that requests are sent to the server every time you frequently access the unified web page, so that the server's recent results can be displayed to the user. When using the above Code in servlet, it must be used before the response. getwriter () method, otherwise it will be invalid.
