Yes, that does look good. However, there's nothing which tells the Nevow
app what URL it is actually working behind which means generated URLs
are incorrect. Now, if proxy also set the 'x-forwarded-from' header then
the Nevow app would work just the same. Hmm, it records 'host' in the
request headers ... perhaps that's supposed to include the port too?
Anyway, thanks for mentioning this.
