Nope, that is _always_ take care of by MHD. You just need to feed the "upload_data" you get in your MHD_AccessHandlerCallback as you receive it to your XML or JSON parser, either incrementally or as a whole. > Is there anyway in libmicrohttpd, I can collect the entire POST message > as it comes / received at socket level? Sure. You should look at GNU Taler (https://git.taler.net/), the exchange and the merchant-backend both use MHD to receive JSON-formatted uploads. The core logic for this is actually from/in GNUnet (https://gnunet.org/git/, gnunet.git, src/json/json_mhd.c). So if you are happy with libjansson, you can link against libgnunetjson (like Taler does) and use that code to parse JSON. XML usage would be analogous (and this is ~200 LOC only). Happy hacking!
