Use of string.match which is NYI in LuaJIT

[edo888]

Hi,

I have noticed that this library uses string.match function which is not supported by LuaJIT: http://wiki.luajit.org/NYI#libraries_string-library

Will this library play nice with LuaJIT or there are other obstacles which I'm not aware of?

Thanks!

@edo888 Yeah, we should use ngx.re.find or ngx.re.match for it. Pull requests welcome!
