Miva - Smart-Breadcrumbs s.http_referer Adjustment Global Pre-Render
<mvt:comment>
|---------------------------------------------------------------------
| SMART-BREADCRUMBS S.HTTP_REFERER ADJUSTMENT
|---------------------------------------------------------------------
| Alters Smart-Breadcrumbs & Category-Tree behavior that always
| loads breadcrumb hierarchies based on s.http_referer; even when
| the refering category is not in the product's hierarchy.
|---------------------------------------------------------------------
| 1.) Check Referring Category
| 2.) Check Current Request's Product
| 3.) Check if the Product is assigned to the Referring Category
| 4.) If the product is not assigned to the referring category,
then set g.Category_Code to a category that the product is assigned to.
