what does this do?

I've had this in my htaccess file for over a year and i don't know what it does. Does anyone know what does it do?

Code:

<Limit GET POST>
order deny,allow
deny from all
allow from all
</Limit>
<Limit PUT DELETE>
order deny,allow
deny from all
</Limit>
AuthName noobgamers.com

I do not know what this does, however that is not from vBSEO. When/where did you add that from?

I think one of my old host added it to my htaccess file awhile ago.
