Clearing cache in servlets

[ford Darcy Jr]

Hi,

I am trying to clear cache using servlets, to prevent duplicate records getting inserted. My servlets has some header variable information relating to username.
I am trying to clear the cache by using:
response.setHeader("Pragma", "No-cache");
response.setHeader("Cache-Control", "no-cache");
response.setDateHeader("Expires", 1);
But, this doesnt seem to work. Can anybody please help.

Thanks

That will not clear the cache. It will tell the browser not to cache the current "page".

Hi,

Thanks for the reply. Can you please tell me, what should I modify in that to get a solution.

Thanks.

There is no way for a response to tell the browser to clear its cache. That is completely under user control.

Hi,

Clearing cache using the response.setHeader("cache", "no-cache"), works fine on tomcat, but doesnt work when moved to weblogic server. Any idea what needs to be used on weblogic server for clearing cache to work.

Thanks

You are mistaking clearing the cache with preventing a page from being cached in the first place.
