Hi:
I'm using Tomcat 6 ( I don't remember the exact release, I hope to be
forgiven by Pid )
I need to modify Cache-Control header in some responses ( forcing them
to not be cached )
What is the best way to do it ?
a) To implement a Valve ( check request context path and if it match
,to modify response header )
b) To implement a filter
c) Others ( any property in Tomcat's configuration files that I don't know )
Thanks and regards
Hi, Jose-
If you have access to the JSP or Java, you might use something like this:
response.setHeader( "Expires", "-1" );
response.setHeader( "Cache-Control", "no-cache" );
See
