Hi Maxim, Thank you so much for your explaination.
I have another question. If i have an empty string in my payload, it skips the phase handler completely. Example: curl -X POST http://localhost/proxy/profile/alice/comment -d '' -H 'Content-Type: application/json' the flag "-d ''" I do doing it at NGX_HTTP_ACCESS_PHASE in the handler. It seems that if "content_length = 0", it skips the access phase handler as well? Does this have to do with what we discussed?
