Hi guys

i have seen lots of topics on this but i cant find a direct answer to my question so here goes.
i will sending data to a server including a logon and password, is this data by default encoded? or do i need to encode it?. if i need to encode it does that mean i have to set a deryption in place on the remote server or is the data just encoded whilst in transit - till it reaches its destination?.

thanks in advance
