Setting response page expire time

[pravin rane]

hi all,
i wanted to set the page expiry time such that for each request the client
browser request server to retrieve the page (now it returns the page which is cached by the browser). i wanted to force client browser to request the
server for each and every request page.

will you please let me know how to do this

thanks in advance.

By setting an appropriate header on the response, you can instruct the browser not to cache the response.

response.setHeader("Cache-Control", "no-cache")
response.setHeader("Pragma", "no-cache")
