SSLEXT, the Struts SSL Extension, provides a convenient mechanism for switching between the HTTP and HTTPS protocols in a Struts application. SSLEXT helps to greatly reduce the overhead incurred by placing of all of your Struts application behind the HTTPS protocol.
See http://sslext.sourceforge.net/.
Note | SSLEXT is covered further, along with Struts security in general, in Chapter 11. |
