I'm looking to do is use some sort of password protection for the form page so that my Hard Drive cannot be filled with useless crap.

I run a password-protected Wiki clone under Apache, using something like the following .htaccess

  Options Includes ExecCGI
  AuthType Basic
  AuthName "Conference Forum"
  AuthUserFile /usr/home/dws/.htpasswd
  ErrorDocument 401 /aye/noauth.html
  <Files ~ "\.cgi$">
    <Limit GET>
      require valid-user
    </Limit>
  </Files>
[download]

Because the posting page is itself produced by a .CGI, and contains some magic stuff in hidden fields, I don't need to limit POST requests. Raw data pages are kept in a subdirectory. The .htaccess in that subdirectory reads

  Order deny,allow
  Deny from all
