Post How to trace and disable the HTTP TRACE method in Apache 1.3.33 with FreeBSD?

I used following configuration settings in ".htaccess" file to disable the HTTP TRACE method, which I found as most common recommended solution.

RewriteEngine On
RewriteRule .* - [F]

My server configurations are as follows:
Webserver: Apache 1.3.33

I want to know how reliable is this?
Is there any simple way, by which I can be sure that it's really working
and the server is now secure from this vulnerability.

One way to test if TRACE has been disabled is to telnet to port 80 (type the stuff in red):

telnet 80
Connected to (
Escape character is '^]'.
<press enter a few times>

If a 400 error is printed then you are secured:

HTTP/1.1 403 Forbidden
Date: Tue, 11 Nov 2008 15:26:33 GMT
Server: Apache/2.0.52 (OS Version)
Accept-Ranges: bytes
Content-Length: 3985
Connection: close
... html
... html

Here is an example of how to use telnet to test HTTP for future reference:
