Strange F5 Reset

If the client is sending an HTTP request with an Expect: 100 header, I think the client must wait until it gets a 100-continue response. If the client isn't waiting, it would probably break the HTTP proxy model in LTM and get reset. As Nitass suggested, if you don't need any HTTP parsing, you could try disabling the HTTP profile either by removing it from the VS or by calling HTTP::disable from an iRule. But really the solution should be to fix the client as it's not correct behavior.
