Not exactly.  The problem is that once we cache a page, Apache never  
calls us again for that page[1].  We can't check for admin status  
because we don't even run--Apache (or whoever) serves the static HTML  
directly to the client.  If we want to do the admin check on the  
server end then we have to completely stop using Rails's page cache,  
and that's a massive performance hit for all users, not just admins.

Putting the admin URL in the page and doing the admin check on the  
client side seems like a low-cost way around this.  The admin URL  
isn't leaking any information--all Typo blogs put it in the same  
place, and the article ID shows up other places in the same file.   
The admin pages need a login to work, so there's really no security  


[1] Until it's swept from the cache due to some other action, that is.
