MiniVend has a facility that adds a parameter called source to the session database for that user.
You should give your partners a source code, which must contain at least one letter character (A-Za-z only). It is placed in the sourcing URL after two semicolons as a query string of:
;;Source1
If this is appended to the
URL with which the user calls MiniVend
it will then be placed in the session identifier source
.
This URL:
C<<>A HREF="http://yourcatalog.com/cgi-bin/yourcat/sp_offer?;;Source1"> Special offer!</A>
Will yield Source1
from the MiniVend tag [data session source].
