Perfect - thanks!


Now, I have thought about this a little while and I don't quite 
understand how it works...?

The key seems to be the rewrite clause - near as I can see, without this 
the error request gets reprocessed by the "location /" section, but the 
rewrite is causing it to terminate that?

Can you teach me to understand this please?

Many thanks!
