This redirect script will accept input from a FORM, either via
METHOD GET or POST, and send a 300-level HTTP status code to
redirect the browser to a new URL.

There are two ways to use a FORM in conjunction with this script:

1.  A list of URLs with a submit button
       <FORM METHOD="POST" ACTION="/cgi-bin/redirect">
       <SELECT NAME="url">
       <OPTION VALUE="http://www.ncsa.uiuc.edu/">NCSA
       <OPTION VALUE="http://hoohoo.ncsa.uiuc.edu/">HTTPd
       <OPTION VALUE="http://www.uiuc.edu/">U of I
       </SELECT>
       <INPUT TYPE="submit" VALUE="Go to URL">
       </FORM>
    In this case, the script will find the input called "url" and
    redirect the browser to this location.

2.  Multiple submit buttons
       <FORM METHOD="POST" ACTION="/cgi-bin/redirect">
       <INPUT TYPE="submit" NAME="http://www.ncsa.uiuc.edu/" VALUE="NCSA">
       <INPUT TYPE="submit" NAME="http://hoohoo.ncsa.uiuc.edu/" VALUE="HTTPd">
       <INPUT TYPE="submit" NAME="http://www.ncsa.uiuc.edu/" VALUE="U of I">
       </FORM>
    In this case, the script will find an input NAME that looks like a URL,
    and redirect the browser to this location.

Either method should work fine, just don't use both within the same FORM.
