That's precisely what I don't find clear in Mike's description. Since he said "take a buffer of data", I assumed "use whatever is in the buffer", and then that's what a fetch does. Of course if it's just to convert strings or so, a converter is better, but that's not my understanding here. > Mike, in such case, you want to have a look at this file: > http://git.haproxy.org/?p=haproxy.git;a=blob_plain;f=src/sample.c;hb=HEAD > and with the upper and lower and any other converter functions. Absolutely. Hopfully Mike will show us what he projected to do once it's done ! Willy
