[Twisted-web] Ticket #2346: HTTP header generation in web2 according to RFC822

Hi all, tekNico and I found a problem with the web2 headers generation code. We opened the ticket #2346 with a patch to the testcase and a patch to web2.http_headers. We are not sure we correctly deciphered RFC 822, where it says: quoted-string = <"> *(qtext/quoted-pair) <"> qtext = <any CHAR excepting <">, "\" & CR, and including linear-white-space> quoted-pair = "\" CHAR Should the "&" character be construed as a linguistic comma: qtext = qtext.replace('\r', '\\\r') or as a logic AND? qtext = qtext.replace('\\\r', '\\\\\r') Thanks.
