Answer 1

This is what you should do

<IfModule mod_rewrite.c>
 RewriteEngine on
 RewriteCond %{HTTP_HOST} !^www.example.com$ [NC]
 RewriteRule ^(.*)$ http://www.example.com/$1 [L,R=301]
</ifModule>

see here for reference

also you can check this for more detail on .htaccess

Answer 2

Open a new IfModule under your mod_expires . You may refer to here

<IfModule mod_expires.c>
// your code
</IfModule>

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTP_HOST} !^www.example.com$ [NC]
RewriteRule ^(.*)$ http://www.example.com/$1 [L,R=301]
</IfModule>

Or Just

<IfModule mod_expires.c>
 // your code
</IfModule>

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

Answer 3

The IfModule checks if the given module is installed and is active. In your example file, its checking if mod_expires.c module exists. If yes do the stuff inside the tag.

Apache rewrites are handled by mod_rewrite.c apache module. So you should do:

<IfModule mod_expires.c>
ExpiresActive On
ExpiresByType image/jpg "access plus 1 year"
ExpiresByType image/jpeg "access plus 1 year"
ExpiresByType image/gif "access plus 1 year"
ExpiresByType image/png "access plus 1 year"
ExpiresByType text/css "access plus 1 month"
ExpiresByType application/pdf "access plus 1 month"
ExpiresByType text/x-javascript "access plus 1 month"
ExpiresByType application/x-shockwave-flash "access plus 1 month"
ExpiresByType image/x-icon "access plus 1 year"
ExpiresDefault "access plus 2 days"
</IfModule>

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTP_HOST} !^www.example.com$ [NC]
RewriteRule ^(.*)$ http://www.example.com/$1 [L,R=301]
</IfModule>

You can get away by removing the tags completely. If there were no tags and you dont have mod_rewrite installed, apache will error out. IfModule gracefully ignores line inside the tag if the required apache module doesn't exist.
