actually, you can use filters to capture the response and then use a
filter to dump the whole thing to the outputstream.
What you'll have to do is create your own buffer to hold the content
and not write to either the jspwriter or the printwriter in the
servlet. the tricky part is this. if you have custom error pages,
you'll have to be careful because there may already be "stuff" in the
buffer.
one of these days I'll have to write an example and post a patch for
the tomcat jsp examples.
