.htaccess Redirection

[reach2raj]

Suppose i have a url like as http://www.example.com, in root there is one folder aaa & in that folder 2 files bbb & ccc.

Now somebody insert following url in addressbar like as:
http://www.example.com/aaa

this page shows up result like as below:
Index /
bbb
ccc

What should i do if anybody open http://www.example.com/aaa url, that doesn't open the list of files of folder. Shoul it possible?

Either add the directive:

Options -Indexes

in /aaa/.htaccess,

or put a file named "index.html" in /aaa/index.html.
