I'd like to know if it is possible to use MHD_create_response_from_callback even if the content length is 0. I tried to pass 0 as first argument to MHD_create_response_from_callback and also returned 0 from the callback, but this made the library to invoke the callback function in an infinite loop. The documentation also states this behavior, but I was curious if there is a way to use MHD_create_response_from_callback even for an empty response body. If not, then I'd suggest to make MHD_create_response_from_callback fail in some way if 0 is passed as size. Thanks for your help.
