Apache SetHandler NONE

I am using the following Apache directive,Now what i am trying to do is that i want to disable all php and html and other extension not to be executed.In the particular directory,But this dosnt seem to be working.

<Directory /var/www/html/home >

# Remove all handlers already set (using SetHandler
# or AddHandler). This should prevent ALL files
# in directory from being executed/interpreted/handled.
SetHandler None

# Remove all other clever options. This is to prevent
# any other surprises.
Options None

# Force .htaccess file to be completely ignored. So
# even if .htaccess file is in directory, it will be
# ignored and cannot override above directives.
AllowOverride None

</Directory>

# ------------

What is your test and how did you determine that it's not working properly ? Did you restart apache after the changes ?

Thx for reply
These setting is advise to be used in apache 777 directory.
Now its working,If u want to stop php execution in specific directory using your web server apache.Do the following.

what i mean from browser.

www.url/dirname/anyname.php
Below directive
1 stop runiing any php file execuation in the defiend directory.
2 remove any cleaver option like symbo link etc.
3 diable .htaccess file in directory.

<Directory /urdirname>

SetHandler default-handler
Options None
AllowOverride None

</Directory>
