This is a Java servlet filter (as per Servlet API 2.3). This filter lets you redirect incoming non-secure requests to the secure equivalent. In other words if requests uses http protocol it will be redirected to the SSL equivalent (https). How to use it: a) download httpsflt.jar and save it in WEB-INF/lib b) describe this filter in your web.xml file. There is one optional parameter port describes
a port for SSL connection in case of it is not 443.
<filter> <filter-name>SecureRedirect</filter-name> <filter-class>com.cj.secure.secureRedirectFilter</filter-class> </filter> or
<filter> <filter-name>SecureRedirect</filter-name> <filter-class>com.cj.secure.secureRedirectFilter</filter-class> <init-param> <param-name>port</param-name> <param-value>your_port_number</param-value> </init-param> </filter> c) describe a mapping for this filter in web.xml
<filter-mapping> <filter-name>SecureRedirect</filter-name> <url-pattern>*.jsp</url-pattern> </filter-mapping> in this case filter will be on for the each .jsp file. So each http request to your jsp files will be redirected to the SSL equivalent (https) For downloading: Filter: httpsflt.jar
