Hai All, Can anybody suggest how to avoid JSPs (Generated HTMLS) to be cached in browsers? I tried various approaches.. Tried - No cache , Expire dates Meta tag stuff - response.setDateHeader stuff But none prevented page from cache... My requirement is if user clicked back I should show page with some message like "No back button allowed for this page" My requirements cannot allow usage of https , protocol, disabling back button stuff or doing some DB related stuff. I read some transction ID / pageID approach in these forums but i did not understood quite clearly. I would appreciate if u can make things clear. Ne other suggestion to clear cache/ Back button is appreciated. TIA Manohar
