annotate src/core/nginx.c @ 9230:e14debe728b0 radix_with_skip
Closed the radix_with_skip branch.
The radix_with_skip branch is an archive of an experiment did in 2008,
and it is no longer relevant. It is now closed to avoid cluttering of
the branches list. If needed, closed branches still can be seen with
"hg branches --closed".
