# Remember that CGI programs have to close out the HTTP header
# (with a pair of newlines), after giving the Content-type:
# and any other relevant or available header information.
# Unlike CGI programs running under Apache, CGI programs under Boa
# should understand some simple HTTP options. The header (and the
# double-newline) should not be printed if the incoming request was
# in HTTP/0.9. Also, we should stop after the header if
# REQUEST_METHOD == "HEAD". Under Apache, nph- programs also have
# to worry about such stuff.
# Feb 3, 2000 -- updated to support POST, and avoid passing
# Malicious HTML Tags as described in CERT's CA-2000-02 advisory.
