There was a problem hiding this comment.
nit: change the comment to "to check that the connection wasn't corrupted." I was here wondering why the connection would be corrupted and how that code was checking that 😝

#339
HEAD requests don't have response bodies, but they do emulate GET requests that may. HttpSysServer was assuming that the emulated GET request would result in a chunked response so it included the Transfer-Encoding: chunked header. However, it forgot to suppress the chunked terminator. This didn't show up in the tests because they weren't expecting additional data on the connection, and they also weren't re-using connections.
Rather than assuming chunking, it now omits the headers and pretends it's a content-length 0 response.
