You need to read the Servlet spec. Great suggestion. I didn't even know that there was a Servlet spec! Very revealing. Your further response summarizes very well the essence of what the Spec has to say on the subject. My intention was to try to come up with a general-purpose forwarding

What I do is build the response in a string instead of writing it to the buffer. Interesting. The string serves as a pseudo buffer which expands in length as required. Very cool. To use this approach one would have to be dealing directly with a servlet, right? IOW, this approach would not be
