Most of my pages are in the Supplemental Index - why?

[Mantees]

Hi all,
I seem to have a problem with my site being normally indexed by google but I can't understand the reasons.
if I search site:mysite.com I see that only my homepage and my RSS feed are indexed regularly, other 80-90 pages are Supplemental Results and the other 500+ of my site are just missing.

I understand that those informations are not enought to help me, but since I can't understand at all why this happened I really can't tell much else.

Mmmhhh..... help? Would be appreciated :)

Have you ever done a redirect for such a thing or is it "silently" appearing?

If I come into our site through "Poodle Predictor" using www.sample.com without the /, I can not go into our subdomain pages, being that it's missing the /.

If I go into the site with the /, I don't have a problem accessing our internal pages..

Just wondering if the bots may have a problem as well..

I have never explicitly added that redirect. I guess the server just "did" it on its own. I always use Apache.
