keepalive: pass the correct arguments to HTTPResponse
python2.7's httplib.HTTPResponse takes the arguments in the following order:
sock, debuglevel, strict, method, buffering
This was previously passing them in as positional and skipped strict, so we set
strict=method. I'm explicitly setting strict=True now to preserve the previous
behavior that has been there since this file was created.
