BTW, you could have written the Lua code like this:

local m = ngx.re.match(ngx.var.request_method, "GET|POST|HEAD", "io")
if not m then
ngx.exit(400)
end

The ngx.re.match uses the same PCRE engine as ngx_rewrite's "if"
anyway. Also, because the regex argument is a constant here, the "o"
flag can be specified to cache the compiled regex object on the global
level.

The debug log data you've provided contains a lot of references to the
location @pretty_urls which is missing from your original nginx.conf
snippet. Could you please provide a minimized but complete nginx.conf
that can reproduce this problem as well as the corresponding debug.log
snippet?

Thanks!
