Method Not Allowed?

Hver gang jeg udføre denne (nedenfor) form, for jeg:
- HTTP/1.1 405 Method not allowed

Script default.asp:

<form action="/action/?login" method="post">
<b><u>B</u>rugernavn</b>
<input name="username" type="text" accesskey="b">
<br /> <br />
<b>Kode<u>o</u>rd</b>
<input name="password" type="password" accesskey="o">
                       
<input type="submit" id="submit" accesskey="l" value="login">
</form>


script action/default.asp:
<%
if request.querystring = "login" then
if request.form("username") = "neo" and request.form("password") = "a000" then
  response.write "correct"
  else
  response.redirect "/?error"
  end if
end if
%>


Hvorfor for jeg det?

- Til alle smarte svar; jeg vil ikke bruge "get" :o)
