.htaccess rewrite - http:// to http://www

I am new to .htaccess redirection.

I am using the below code

Options +FollowSymlinks
RewriteEngine on
rewritecond %{http_host} ^example.com [nc]
rewriterule ^(.*)$ http://www.example.com/$1 [r=301,nc]

But when i hit the URL http://example.com/folder/file.php i'm getting redirected to http://www.example.com/file.php which is开发者_JAVA百科 wrong.

Can someone please help me with this

Help is greatly apreciated

Thanks

Alright can you try this in your .htaccess or apache conf file:

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

There are some typos and some unescaped characters, but most important you're missing a needed "$" character in that *rewritecond %{http_host} ^example.com [nc]* line.

Here is your code "as it should have been":

Options +FollowSymlinks
RewriteEngine on
RewriteCond %{HTTP_HOST} ^example\.com$ [NC]
RewriteRule ^(.*)$ http://www.example.com/$1 [R=301,NC]

Though, I personally use and would recommend doing it like this:

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

That should get you going... ;)
