Yup, I have plenty of on() calls for various different URIs, and within each there is a bunch of processing of the args to do various things.
I was hoping to add in one command that pulls the uri+args and forwards them to another IP address, so that I can either duplicate the device, or log it. Hence would ideally be able to just take the string of the full request, as opposed to re-assembling it.
I understand the desire to have the full code to aid your understanding, but there are several thousand lines of code, hence thought summarising it into the usage of the functions was easiest. I think I was just assuming that the entire request string must have existed and hence could be retrieved easily through a particular function, but perhaps it is immediately processed into the uri/argName/arg functions.
