The documentation for mod_cgi at http://httpd.apache.org/docs/current/mod/mod_cgi.html still refers to the CGI specification which was hosted at hoohoo.ncsa.uiuc.edu. That hostname no longer resolves, so presumably this should be changed to refer to the CGI RFC 3875. See also bugs #47455 and #49152.
