block a subdirectory

[concepts99]

I have it as

domainname/subdirectory/subdirectory2

I only want to block subdirectory2

Do I use

disallow: /subdirectory/subdirectory2

or

disallow: /subdirectory/subdirector2/

[Smalldude]

disallow: /subdirectory/subdirectory2 this is right

Remember
disallow: /subdirectory/subdirectory2/ will allow it into subdir2 and block directories in subdir2
