caching static objects

[Kimberly McKinnis]

We are running Tomcat-standalone and are having some caching issues. It
appears to be a browser issue, but there's got to be some workaround.
We've got the headers set to pragma nocache, but it continues to cache
objects, such as charts that are created dynamically. I suppose this
wouldn't be an issue if the code worked with Apache. Also, creating
unique identifiers for each object has been shot down. Does anyone know
of a way to get server.xml to set each object not to cache? Thanks.
