I should add that the reason I need to identify external requests is so I can pass on a list to my host provider that will be added to a “permitted” list.
Of course the major drawback here is that the whole trackback/ping functionality will be permanently broken (unless by chance I blog and link to a site that has been previously approved)
The more I look into this change the more I think I’ll be ditching my host provider and moving the site…
