I just did a few tests with current versions IE/FF/Op/Saf/Chrome.


1) some pick the first Content-Length header (Op/Chr/Saf/IE), FF picks 
the second

2) some close the connection (Op/IE), some do not

3) most parse multiple lenghts in a single header just like multiple 
headers, except for FF which then ignores the header and reads until EOF

4) all are ok with multiple header instances having the same value

I think this is good news in that there's no interop for broken 
messages, thus whatever we decide to do is unlikely to break existing 

Best regards, Julian
