Thanks Maxim, that's exactly what I did do, as my follow-up post 
mentioned. All sorted now and working wonderfully. There is one other 
thing, though...At the moment, I have two location blocks with identical 
content, in order to match two different patterns. One matches all URLs 
starting with certain strings, e.g.

location ~ ^/(abc|def){

The other is an exact match for the top level page:

location = /{

Ideally I would like to use a single pattern which combined both. I 
thought to use regex end markers instead of the exact match, but I'm not 
sure if it's syntactically correct (and this is a very busy server i 
don't want to mess about with too much experimenting). So would 
something like this work?

location ~ (^/abc|^/def/|^/$)
