.htaccess Rewrite question

Hi,

I am trying to redirect my non www version of the site to the www version

http://infatex.com to http://www.infatex.com

I used this code, and it works well:

RewriteEngine on
RewriteCond %{HTTP_HOST} ^infatex\.com
RewriteRule (.*) http://www.infatex.com/$1 [R=permanent,L]

but i saw some people are using 301 redirect, that looks like this:

RewriteCond %{HTTP_HOST} .
RewriteCond %{HTTP_HOST} !^www\.example\.com [NC]
RewriteRule (.*) http://www.example.com/$1 [R=301,L]


Should i use [R=permanent,L] or [R=301,L] ?

and one more question:

What should i use to redirect www.infatex.com/index.php to www.infatex.com ???
Thanks

 

Permanent is a symbolic name for 301 redirect, so this codes are equivalent.

 

That's what i thought Thank you!
