string circulation_pro_purchase_url( service_id, referer_url )
After tncms-mediaspan 0.2.0 this acts no different from cms.mediaspan.circulation_pro_self_service_url, so use that instead because this function is deprecated and may be removed without notice in a future release.
Get the full URL to which users should be directed to log into an account unknown in BLOX.
A non-caching controller URL which will check all Mediaspan services and forward the user appropriately will be returned unconditionally.
Pass a valid MediaSpan service ID as this to restrict checks this would make and generating a URL use only that service.
Optional referrer URL to override REQUEST referer_url. If omitted, attempts to fill from REQUEST. If neither found, referer_url will not be sent in the URL params.
The URL to which users should be directed to log into and create an account on the circulation pro system.
IMPORTANT: Returns null unconditionally if not enabled as per cms.mediaspan.circulation_pro_enabled().
