Options +FollowSymLinks

Do I need this?

[riverstyx]

I'm using the following to redirect non-www to www version of site:

RewriteEngine on
RewriteCond %{HTTP_HOST} ^mydomain\.com
RewriteRule (.*) [mydomain.com...] [R=301,L]

I see
Options +FollowSymLinks
often referenced as a precursor. Why? Do I need to add it for some reason?

TIA,

RS

Only if the rewrite doesn't work without it, try it without it first, if it works, you don't need it.
