# If $VALID_CREDS_FILE exists in $HTTPD_ROOT_PATH, consider each line as a valid

# valid HTTP Authorization header value. For example:

# Basic YWxpY2U6c2VjcmV0LXBhc3N3ZA==
#
# If $CHALLENGE_FILE exists in $HTTPD_ROOT_PATH, output the contents as headers
# in a 401 response if no valid authentication credentials were included in the

#
# WWW-Authenticate: Bearer authorize_uri="id.example.com" p=1 q=0
# WWW-Authenticate: Basic realm="example.com"

# No Parsed Headers (NPH) script, we must return a real HTTP
# status line.
# This is only a test script, so we don't bother to check for
# the actual status from git-http-backend and always return 200.
