Hi all,
Using Jigsaw proxy (with no cache) I encountered several problematic

    a. http://customnews.cnn.com
                 Netscape browser gets "Document contains no data"

    b. http://www-il.radview.com
                Netscape browser gets "Document contains no data"

    c. http://customnews.cnn.com/cnews/pna.myhome
                Netscape browser gets "Document contains no data"

    In all cases getting these url's directly from Netscape gives
    correct HTMLs.

    A bit of digging exposed the fact that in all cases there was a
    200 OK status accepted and probably complete headers but also an
    IOException of "socket was closed".
   Could this has to do something with zero content-length?

    http://www1.playboy.com/ads/entrepreneur2.cgi  (a bit embarracing)
            Results (after a redirection) in:
    'An HTTP error occured while getting

    Details "expecting :(58) got (10) context:
Netscape-Communications/1.1 ". '

    Without jigsaw proxy I get the first redirection, then another one
to        http://www.entrepreneurmag.com" which gave me a correct HTML.
    This problem is definately a MimeParser problem. After some more
digging I found
    out that it's source is the "expect" method from the
"parse822HeaderName" method.


    Is received OK with or without Jigsaw but I discovered that instead
of getting
    content-type of 'text/html' Jigsaw gets null content-type. I guess
it has something to do
    with wrong parsing.

I read a previous mail about the "Document contains no data" problem,
which stated that it's a known bug in 1alpha5 Jigsaw but I couldn't find
any further documentation about this bug, nor any
way to solve it.
I know these cases may be cases of non perfect HTTP, but I would like my
proxy to be
able to recover from such cases at least the way the Netscape browser

I'm using JDK 1.0.2 and 1.1.2 on NT4.0 .
Thank you for any help.
