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 as a query string of:
mv_pc=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?mv_pc=Source1"> Special offer!</A>
Will yield Source1
from the MiniVend tag [data session source].
The Minivend 3 idiom ?;;Source1 continues to be supported, so existing partner sites should work without change.
