I am starting to get a collection of HTML files that require some
filtering before they get sent to the client. One good example is
a filter that handles tutorial-style questions. Sometimes a
question will have hints that get revealed, in-line, only when a
reader requests them. In these cases, you probably do not want to
see these nodes put on the history list.
In cases like these, its the server that could have something to say
about it, advising the client not to keep a history for certain
nodes (or variations, really).
