This is actually on the Struts ToDo list. See "HTML No-Cache Support" here:
http://jakarta.apache.org/struts/proposals/todo-1.1.html This functionality will not be incorporated into Struts 1.1, but it is certainly something we can look at after 1.1 Final is released. In the meantime, feel free to develop a proposal. ;-) -- Martin Cooper > -----Original Message----- > From: BONNET Francois-Xavier > [mailto:[EMAIL PROTECTED]] > Sent: Monday, September 23, 2002 7:55 AM > To: [EMAIL PROTECTED] > Subject: Browser's cache > > > Hi everyone, > > > A good way to improve applications performances is to use > browsers caches, > reusing a cached page makes you save a lot of CPU and network traffic. > > HTTP protocol is rich enough to let you decide when you want > a page to be > recalculated or retreived from cache but Struts does not take > advantage of > this : you can only set the parameter "nocache" of > ActionServlet to "true" > or "false".
