How does internal redirecting work?

My site http://www.mrairsoft.com uses a redirect system, so if somebody types in mrairsoft.com it goes to https://www.mrairsoft.com, and if somebody times in www.mrairsoft.com it goes to https://www.mrairsoft.com (I want it so that if you type mrairsoft.com it goes to https://www.mrairsoft.com, notice the www). Anyways, does having this kind of redirect going on (linking with http://mrairsoft.com and redirecting to https://mrairsoft.com) have any negative effect on SEO?

 

I meant to say "How does internal redirecting affect SEO" but I was tired and named the thread poorly.

 

I'm assuming those are 301 redirects your mentioning. (permanent redirects) If so, with time they will carry the Page Rank weight from one page to the other. And that is pretty much the affect that it will have, you are telling the SE's that the page moved.

 

Well, we've put this code:

RewriteEngine On
RewriteCond %{HTTPS} !=on
RewriteRule ^(.*) https://%{SERVER_NAME}/$1 [R,L]

Code (markup):

Into the htaccess folder. I'm not sure if that is a 301 redirect or not.
