if you don't want to deal with redirects/forwards, and you need to keep info from being resubmitted, then this works. In the implicit request object, certain headers are sent during a refresh that aren't sent during a normal request. Or in the case of IE, the "Accept" header is different for refreshes than it is for normal requests. So test for these headers. � IE: "accept" == "/" � Opera: the "cache-control" header exists � Netscape/Mozilla: the "pragma" header exists The method for recovering the headers must be getHeader instead of get Parameter. So, your code will look like: if ((!request.getHeader("accept").equals("/")) && // bypass I.E. reload (request.getHeader("pragma") == null) && // bypass Netscape reload (request.getHeader("cache-control") == null)) { // bypass Opera reload add.data.to.db }
