Hi Fish (and all W3C mailing list),
I saw in the W3C mailing list your comment on the content-length in
multipart/mixed.
I think you are very expert of this argument and then I'd like to ask you
how to calculate the value of the content-length in a multipart/related
type.
I have to send to a Wap Gateway an HTTP message where the content is a
multipart/related type; so this message must contain the content-length
header.

This is and example:

POST /cgi-bin/wap_push.cgi HTTP/1.1
Host: www.wireless-network.com
Date: Sun, 16 May 1999 18:13:23 GMT
Content-Type: multipart/related; boundary=asdlfkjiurwghasf;
type="application/xml"
Content-Length: (???????????)

--asdlfkjiurwghasf
Content-Type: application/xml
<?xml version="1.0"?>
<!DOCTYPE pap PUBLIC "-//WAPFORUM//DTD PAP 1.0//EN"
"http://www.wapforum.org/DTD/pap_1.0.dtd">
<pap>
..control..
</pap>

--asdlfkjiurwghasf
Content-Type: text/vnd.wap.wml
<?xml version="1.0"?>
<!DOCTYPE WML PUBLIC "-//WAPFORUM//DTD WML 1.1//EN"
"http://www.wapforum.org/DTD/wml_1.1.xml">
<wml>
<card>
<p>Hello world!</p>
</card>
</wml>
--asdlfkjiurwghasf--

The rows of the boundary (called "--asdlfkjiurwghasf") are included in the
content-length value?
And the rows called "Content-Type: application/xml" and
"Content-Type: text/vnd.wap.wml"?

Thanks in advance. (and sorry for my bad English)
