Description
This directive allows you to specify a prioritised list of CGI
variables (sources) from which to set the source (affiliate) name.
If multiple sources are specified,
then each will be searched in sequence,
when a page is loaded,
until a match is found.
Source can be the name of a CGI variable or any of the following:
| Source
|
Description
|
| mv_pc
|
Has the current special meaning of mv_pc.
For instance, RESET is special,
as are values that contain only digits. |
| cookie-NAME |
Check the named cookie. |
| session
|
Stop processing the list if session already exists,
do not check any further variables. |
| session-NAME |
Stop processing the list if named session variable is set. |
Examples
Check mv_pc first,
and then mv_source if mv_pc is not set (default action):
|
SourcePriority mv_pc mv_source
|
Check the MV_SOURCE cookie for an affiliate name
as well as the other defaults:
|
SourcePriority mv_pc mv_source cookie-MV_SOURCE
|
Check mv_source and the MV_SOURCE cookie
(don't check mv_pc):
|
SourcePriority mv_source cookie-MV_SOURCE
|
Check the CGI variable affid instead.
Don't check anything else:
Say you send affiliate traffic to other sites,
and you don't want those sites to get credit for sales if a customer
follows a banner from them back to your site:
|
SourcePriority session mv_pc mv_source
|
If you want affiliates who use the specialsource CGI
variable instead of mv_source to get special treatment and override
customers who already have sessions:
|
SourcePriority specialsource session mv_pc mv_source
|
If you want to allow affiliates to get credit if there is a session,
but only if no other affiliate is already set:
|
SourcePriority session-source mv_pc mv_source
|
