ProxySG Content Policy Language Guide
block_category( )
This property has been deprecated.
In current CPL, the use of block_category(category_list) has been replaced by
category=category_list exception(content_filter_denied)
However, block_category() will be overridden by content_filter_override(yes), while this is not the case for the replacement CPL code shown above. Note that content_filter_override() is also deprecated.
