Weird cgi error

Mon Feb 25 02:40:25 EST 2008

I uploaded the following script, called "test.py", to my webhost.
It works find except when I input the string "python ".  Note that's
the word "python" followed by a space.  If I submit that I get a 403
error.  It seems to work fine with any other string.
What's going on here?

Here's the script in action: http://crookedgames.com/cgi-bin/test.py

Here's the code:

#!/usr/bin/python
print "Content-Type: text/html\n"
print """
<html>
<body>
  <form action="test.py" method="post">
    <textarea name="data">
    </textarea>
  <INPUT type="submit" value="Submit">
  </form>
</body>
</html>
"""
