hi, this sounds like you don't use a redirect but answer the login-post-request with html. When an user hits browser refresh the post request ist submitted again but the action misses some data at this time. I suggest to use a redirect after login to show the user start page. http://struts.apache.org/docs/redirect-action-result.html regards, Christoph This Email was scanned by Sophos Anti Virus
