I think this is what you are after. I don't have a good way to test. The content can be modified or removed as it is the body of the response. HTTP::respond 417 -version 1.1 on its own will return "HTTP/1.1 417 Expectation Failed" if that is all you want.

when HTTP_REQUEST { if { [string tolower [HTTP::header "Expect"]] equals "100-continue" } { HTTP::respond -version 1.1 417 content "Expectation Failed" } }

Thanks mimlo for your reply. It was really helpful. the irule works with minor modification. Please see below: when HTTP_REQUEST { if { [string tolower [HTTP::header "Expect"]] equals "100-continue" } { HTTP::respond 417 -version 1.1 content "Expectation Failed" } } The problem I am now facinfg is it is not closing the connection after sending the response. How do I get it to close the connection after responding?

Add an HTTP::close on the next line after the HTTP::respond
