Yes this works.  I can see that IE5 does not cache the page locally,
by looking in Temporary Internet Files.

I realize now though, that what I really need is to drop certain pages
out of the browser "back" chain.

For instance say I have three pages:

   A --  B  --  C


Once the user selects page C, I don't want them to see page B with the
browser back button.  If they use the back button, I want them to jump
from C all the way back to A.

IOW, I want to "unlink" B from the chain. Is that possible?

[PHP] Browser cache and form with $PHP_SELF

[Egan]

Using $PHP_SELF, I have a form that calls itself until the user gets
all the input right.  Each time the user corrects some field and
resubmits, the browser builds a cache of pages, as you can see with
the browser back button.

Is there a way to make the browser clear the cache on every submission
so the user cannot go back to any previous page?  Seems like I've seen
sites that do this, but I'm not sure how they do it.
