Have a look at section 3.4.1 (Clarifications>>Quoting): Within these constructs, quoting is REQUIRED for CR and "\" and for the character(s) that delimit the token (e.g., "(" and ")" for a comment). So, they're saying to backslash escape CR, "\" and double-quote for quoted-strings. HTH, --Grant On 2 Jan, 2007, at 09:19, david mugnai wrote:

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 = , "\" & 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.
