Disable HTML page caching in Tapestry 3.0.3 application

[JIM WEAVER <we...@gmail.com>]

This is browser client-side caching I'm trying to disable rather than 
Tapestry server-side page cachine.

For our JSP apps, either a custom tag or servlet filter is used to execute 
the something like:

httpResponse.setHeader("Pragma", "no-cache");
httpResponse.setDateHeader("Expires", 0);
httpResponse.setHeader("Cache-Control", "no-cache");

I tried that code in a servlet filter with our tapestry app, and it executes 
but appears to have no effect. I've also tried adding it to pageBeginRender 
of select pages, and using meta tags in the html header instead of setting 
the response. All no effect.

I suspect my problem has nothing to do with Tapestry, but I can't figure 
what I'm doing wrong.

Anyone doing this currently?
