1. The client can't be modified. 2. The client doesn't send "Expect". 3. The client claims to use HTTP1.1 (but ironically doesn't support 100 contine!) Will apache still send random 100 continues? IIS does that. The RFC 2616 seems to allow it. So if apache does send 100 continue without Expects', I want to know if there's any way to suppress it at all. -----Original Message----- From: André Malo [mailto:nd@xxxxxxxxx] Sent: Friday, 17 August 2007 5:59 PM To: users@xxxxxxxxxxxxxxxx Subject: Re: suppressing HTTP 100 continue * Jimmy Lee wrote: > I'm working with some devices that can't handle 100 continues. > > Is there a way to apply filters to apache to stop it from sending HTTP > 100?

So, teach the clients to not send the Expect header and/or use HTTP/1.0. Apache does not send the header without the client "Expect"ing it.
