Hi All, How can I add a header, if it is not set by the application. I want to add Cache-Control header to all http responses, if it is not set by the back-end application like PHP or application server like tomcat. I tried a combination of SetEnvIf and Header, but SetEnvIf is only fused for requests. Can any one please guide me in the right path? (Sorrmy English is poor) Thanks in advance.
