Actually, I had already implemented the underpinnings of a URL
history feature in MV4. (For the source-readers out there, look for the
url_history routine in bin/minivend.) It is designed to solve the common
basket problem. You can either do:

    <A HREF="[history-scan
		exclude="__ORDER_STYLE/"
		default=browse]">Continue shopping</A>

to look for the first page not in the basket area, or

    <A HREF="[history-scan find="scan/" default=index]">Continue shopping</A>

to find the last scan/ page, or some combination of the above. Or you 
could do:

    [set Continue Shopping]
	[bounce href="[history-scan find='scan/' default=index]"]
    [/set]

It preserves your CGI variables, with the exception of session ID and
mv_credit_card_number and others in the Ignore settings, so it should
be just like re-submitting the page.

I was looking at putting the tag in (probably a UserTag) after your message,
but found a bug in the History save mechanism. Look for it in a future demo.

Best,
Mike
