I heard this "centralise" mantra many times. Believe me, it works until
your configuration fits on screen or two. When it grows, every, note,
EVERY configuration modification becames investigation of
configuration dependences. I have an configuraiton with 180 locaitons.
When I need to add some functionality, I simply add location and
that is all. I do not look through whole 90K file.

Why ? Because I

1) use only locations without regex.
2) do not use rewrite's at all.

If I need to change a proxied server name or something else, I use simple
find/replace in VIM. This is very easy, it's much easy than investigation
of configuration dependences on every change.

error_page is faster because it does not make syscall.
