[ic] Processing order with no items

[Joachim Leidinger]

Hi List,

I use an external Payment Gateway and this Payment Gateway send the
results back to my special IC pages. In this special IC page, I've

....
[if scratch successcall]
[tmp url][area href=process secure=1 form="
mv_todo=submit
mv_order_route=log main copy_user
mv_order_report=../etc/report.html
mv_order_receipt=../etc/receipt.html
"][/tmp]
 [bounce href="[scratch url]"]
[/if]

to finish the order and to get the receipt page. If I reload the receipt
page in my browser, I get a new order number with the whole stuff of
mail_receipt, report, receipt.html with no items once more, because IC
is processing such url like

If I patch bin/interchange like

IC will not process the whole order routes and send any emails once more
and will not create a new order number. With the above patch, I get the
normal behavior of IC, if I reload the receipt page several times.

If there is an item in the cart, I get the debug messages like

--------- snip -------
main:debug: Default order route=default
main:debug: Default order route=default
main:debug: Profile status status=1 final=1 errors=
main:debug: Routing order, pre-check
main:debug: Routing status status=1 final=1 errors=
main:debug: Routing order default
main:debug: Order number=TEST0127
main:debug: Order number=TEST0127, result_hash={
  'supplant' => '1',
  'master' => '1',
  'cascade' => 'log main copy_user',
  'email' => 'spam@nospammer.spam',
  'empty' => '1'
}

main:debug: selected receipt=../etc/receipt.html
main:debug: not_displayed=0
main:debug: returning order_number=TEST0127, not_displayed=0
--------- snip -------

If I reload the receipt pages several times with the patched
bin/interchange, I get

--------- snip -------
main:debug: Default order route=default
main:debug: Venditems = 0
main:debug: Default order route=default
main:debug: Venditems = 0
main:debug: Default order route=default
main:debug: Venditems = 0
....
--------- snip -------

What do you think about the different behavior and patch?
Any comments?

Thanks!
