Mod Rewrite htaccess from NON-WWW to WWW is not working

ok i'm trying to redirect my domain http://iphonewifihotspots.info to this:

www.iphonewifihotspots.info
(so includes the WWW)


I tried this:

RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} !^www\.iphonewifihotspots\.info [NC]
RewriteRule ^(.*) http://www.iphonewifihotspots.info/$1 [L,R=301]

But it doesn't work. It justs go to this:

http://www.iphonewifihotspots.info/iphonewifihotspots/
(it has a forward slash after it and some more text. and it is 404 page not found)

I've also tried this:

RewriteEngine On
RewriteCond %{HTTP_HOST} ^www\.iphonewifihotspots\.info$ [NC]
RewriteRule ^(.*)$ http://iphonewifihotspots.info/$1 [R=301,L]


But it still doesn't work. it goes to this:
http://www.iphonewifihotspots.info/iphonewifihotspots/
(which goes to 404 page not found)




What is wrong? I'm hosted with hostgator on a shared server.

 

Those codes look more like you're trying to get rid of the www!!!

RewriteEngine on
RewriteCond %{HTTP_HOST} ^iphonewifihotspots\.info [NC]
RewriteRule ^(.*)$ http://www.iphonewifihotspots.info/$1 [R=301,L]

 

RewriteEngine on

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

 

i've solved my problem. i was modifying the htaccess from my public html folder when i should have been modifying the htaccess in my subdomain folder.
