My problem is that I would like to know the size of the file before downloading it with http protocol. I know there is a wip_getFileSize(channel, eventhandler) function (in the ftp example in wip datasheet) but I cannot use it since httpCreateClient gets NULL for the eventhandler, so there cannot be any handler for the wip_getFileSize(channel, eventhandler) function like in ftp example… Any ideas please?
