If you mean a public web page with normal Internet security
restrictions you cannot launch an exe at all (for very obvious
safety/security reasons).

If you are running this on the server, then this is the wrong place.
JavaScript has four things in common with JavaServer Pages - the
letters "J", "A", "V" and another "A".

On the client side, running executables with JavaScript is pretty much
impossible in a standard security environment, but as you seem to be
writing the executable in Java you might have some luck if you google
for "Java Web Start" (which also has nothing to do with JavaScript).

I presume that means one cannot create a file from scratch to use for
variable memory common to a number of web pages that call each other?
If true, and since cookies are said to be not reliable, then it would
seem to be impossible for a 100% client-side JavaScript based web page
set to have shared variables.
If that is possible, then how could it be implimented?
I ask because i am trying to save a goodly chunk of money that would
be required for a server-side solution.

No, I mean that a public web page with normal Internet security cannot
launch an arbitrary executable in the client computer.

That would probably depend upon what 'shared variables' was supposed to
be referring to.

Your specification for 'it'?

There is a difference between not spending money and saving money
(particularly over the longer term).

Not on an Internet site. If it's Intranet you have possibilities.

True, cookies are not reliable. Put the site in a hidden frame scenario
and keep your variables in the frameset.

See above.

PHP and Apache are free so where is that "goodly chunk of money" going
to be spent?

My ISP wants $$ to impliment security on my proposed web pages.
I do not want anyone to type in the full URL of any of the web pages
and have them work - except the index.html "root".
I have figured out a way that page#1 can "call" page#2 which can
"call" page#3 etc and one can use the back button successfully - but the
(stored) state variable can be used to prevent any other kind of entry.

Your ISP or your hosting company? All your ISP does is provide you with
an Internet connection, hence the ISP - Internet Service Provider.

Get a Broadband Connection (preferably Cable)
Download Apache and PHP
Create your own server.

Simple stuff and it only costs you a Broadband connection.

You can't reliably do that on the client. If you want limited access you
have to do it on the server.

If your "security" depends on JS (or any other client side technology)
then you don't have security, you have a false sense of security.
