Dear WG,

I have a question on the Expect header section 9.2 in HTTPbis 16[1]

Is my understanding correct:

1. A proxy that finds an expectation extension in the Expect header that it does understand but cannot meet must respond 417
2. A proxy that finds an expectation extension in the Expect header that it does not understand ignores the extension
