You told of “pages”, meaning documents, being “active”, which is utter 
nonsense with a stateless protocol.  The document resource is served, i.e. 
transferred from the server to the client, and that is it.  Only a client-
side *script* can be “active”, i.e. running.

You do not have a page, you have a document.

There is no “Javascript”, but, for the sake of discussion, let us continue 
under the assumption that you wrote “JavaScript”, even though even that term 
is insufficient to describe the situation.

Good idea.

ACK.  (Some people with less understanding of English appear to have 
misunderstood you here.  Keep in mind that this is an international 
newsgroup, so it is best to avoid the more peculiar idioms of the
language in order not to be misunderstood.)

Yes.
