Thanks, I am aware of that.  What is missing from the docs is the
format for multiple sub_filter entries.

Is it:

a) sub_filter "matchA" "replaceA" "matchB" "replaceB";

b) sub_filter "matchA" "replaceA"
     sub_filter "matchB" "replaceB"

c) sub_fitler "match1" "match2" "match3" "replaceAll"

d) Only 1 sub_filter allowed per location or server

And then there's the issue of sub_filter_last_modified and
sub_filter_once applying to all, or just the preceding or the
following entry?

Multiple sub_filters is a great addition, docs are unclear on usage.  :-)
