Update p5-libwww to 5.53

2001-04-10   Gisle Aas <gisle@ActiveState.com>

Release 5.53

    LWP::Simple::get() could sometimes return nothing on failure in
    list context.  Now it always returns 'undef'.

    HTTP::Cookies does not request 2 dots on domain names any more.
    New option to hide the Cookie2 header.  Cookie2 header now quote
    the version number. Updated reference to RFC 2965.

    Support for embedded userinfo in http proxy URIs.  It means that
    you know can set up your proxy with things like:
        http_proxy="http://proxyuser:proxypass@proxyhost:port"
    Patch by John Klar <j.klar@xpedite.com>.

    Experimental HTTP/1.1 support.  New module called Net::HTTP that
    provide the lower level interface and a LWP::Protocol::http11
    module that builds on it.  The HTTP/1.1 protocol module must be
    loaded and registered explicitly, otherwise the old and trustworthy
    HTTP/1.0 module will be used.

    LWP::Protocol::GHTTP will try to use the get_headers() methods
    so that it can actually extract all the headers.

Release 5.52

    HTTP::Header: new method $h->init_header() that will only
    set the header if it is not already set.  Some shuffling
    around in the code.

    LWP::UserAgent will not override 'User-Agent', 'From'
    or 'Range' headers if they are explicitly set in the
    request passed in.

    HTML::Form tries to optimize parsing be restricting the
    tags that are reported by HTML::Parser.  Will need
    HTML::Parser v3.19_93 or better for this to actually
    have any effect.

    LWP::Protocol::ftp now deals with path parameters again.
    It means that you can append ";type=a" to ftp-URI and
    it will download the document in ASCII mode.

    If the server output multiple Location headers on a redirect,
    ignore all but the first one.

    Extract cookies failed on request URIs with empty paths.
    This was only triggered if you used URI objects directly in
    scripts.

    This change was actually part of 5.51:  Fix qop="auth"
    handling for Digest authentication.

Release 5.51

    SECURITY FIX: If LWP::UserAgent::env_proxy is called in a CGI
    environment, the case-insensitivity when looking for "http_proxy"
    permits "HTTP_PROXY" to be found, but this can be trivially set by the
    web client using the "Proxy:" header.  The fix applied is that
    $ENV{HTTP_PROXY} is not longer honored for CGI scripts.
    The CGI_HTTP_PROXY environment variable can be used instead.
    Problem reported by Randal L. Schwartz.

    NOTE: It is recommended that everybody that use LWP::UserAgent
          (including LWP::Simple) in CGI scripts upgrade to this release.

    Explicit setting of action on HTML::Form had no effect because
    of a code typo.  Patch by BooK <book@netcourrier.com>.

    HTTP::Daemon: The CONNECT method need special treatment because
    it does not provide a URI as argument (just a "hostname:port").
    The non-upward compatibility warning is that you must now call
    $request->url->host_port to get the host/port string for CONNECT,
    rather than calling $request->url and using the entire string.
    Based on patch from Randal L. Schwartz <merlyn@stonehenge.com>

HTTP::Daemon: Create self URL based on $self->sockaddr.  This works
    better when LocalAddr is used to specify the port number.  Based on
    patch from Ben Low <ben@snrc.uow.edu.au>.

    Avoid potential '<FILE> chunk 1' messages at the end of the response
    'message'.
