Wireshark-users: [Wireshark-users] HTTP Filter for 401 response

Date: Mon, 24 Sep 2007 10:57:44 -0500 (CDT)
I have version 0.99.6a installed on WinXpSP2. The default installation of
wireshark does not display the HTTP 401 Authorization Required using the
HTTP filter; it is labeled TCP. Do I need to change a preference or some
other setting so that HTTP filter includes the 401?
Thanks,
Steve
