Hi all, I've got a bit of a problem understanding how to use MHD_lookup_connection_value for getting access to trailing keys. The documentation says: > A value of NULL for key can be used to lookup ’trailing’ values without a key, > for example if a URI is of the form “http://example.com/?trailer”, a key of > NULL > can be used to access “tailer" The function returns NULL if no matching item > was found.
I'd expect that MHD_lookup_connection_value(connection, MHD_GET_ARGUMENT_KIND, NULL) would return "trailer", which is not the case. It returns NULL. During a debug session, it came up that this particular request's /headers_received/ seems to be processed like this: kind = MHD_GET_ARGUMENT_KIND, header = "trailer", value = NULL (...) The first for-loop in MHD_lookup_connection_value_n would stop once it found a header being NULL (which is not the case here). Furthermore, if it actually found the correct key-value-pair, it would return the value, which is NULL here. Is there a way to access "trailer" as it is described in the documentation? Thanks, best regards, Paul
