redirect non-www to www

is my code correct

[proboscis]

Hi,

This is supposed to redirect my index.shtml page to /

and redirect all non-www pages to the www version

Is it all correct?

Thanks!

That will work, and it will fix all possible non-canonical variations.

In place of

shtml

I use

s?html? 

so that requests for index.shtml .html and .htm are all redirected.

In some circumstances the three conditions in the www canonicalisation rule can be simplified to:

RewriteCond %{HTTP_HOST} !^(www\.example\.com)?$ 

You code will work as is, so these suggestions are merely a matter of preference.

Good, thank you for the tips :) I didn't know I could do that.
