Is mod_auth_cas meant to assume the input filter can be called more than once per request? I have seen it recently somewhere else, in CGI context where the CGI was not looping over stdin. I don't recall the exact cause, but it's something like another module peeking to see if data is ready ion the connection. The 1 byte it reads is consumed and set aside, but weaved back in to the next real read. It's fair to say any input filter has to be prepared to be called multiple times. --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscribe@xxxxxxxxxxxxxxxx For additional commands, e-mail: users-help@xxxxxxxxxxxxxxxx
