Google is your friend, http://java.sun.com/products/servlet/2.2/javadoc/javax/servlet/http/HttpServletResponse.html#sendRedirect(java.lang.String)
You can get the URL with a method in the HttpServletRequest class, getRequestURL(), substitute "https" for "http" in there and redirect to that page with response.sendRedirect(..). That will exclude any parameters, however but, if needed, implementing that is left as an excercise... In HTTP pages don't send data to pages, but rather browsers get responses from servers by sending requests. The problem with this kind of interceptor is, that if an interceptor catches a request that is not secure, then the request (and all its parameters, more importantly) has already travelled across the internet from the browser to the server unprotected. If that request is redirected to an SSL-protected page, it will only make the browser send the request again, protected this time, but as it already has travelled across the lines with no protection, this approach is not actually protecting the data in the request. Such a filter (or interceptor) should only be used for testing that the page flow is working with SSL all the time, not for any actual production use (or at least I can't imagine a situation where it would fit).

Hi Tony, Thanks for the reply. I use an interceptor to check the HttpServletRequest's isSecure() method in order to determine it if is secure or not. I've never used the HttpServletResponse object and I'm not sure how to redirect to the same address but with https. The redirecting won't be to only one page, but will depend on the request. All of the pages in my web app are controlled by actions, so there's no data being sent from one page to another without the original page being intercepted to check for ssl usage. Please let me know how to use HttpServletResponse for redirecting. Thanks, Session > It may be an ugly hack, but it has worked for some of my actions.
