godaddy / htacces / weird results (yes, i've searched and looked at all the posts!)

[eluser]cityzen[/eluser]
Ok, so i finally have this thing "working" but I really like to understand how/why it's working rather than saying "ok, cool!".

I can access my pages all by http://www.mysite.com/admin/index.php?/foo/bar/

What's the dilly with the "?" ? I know what a ? does, but i'm not following why that being there is helping?

Also, apparently godaddy caches their htaccess files on an hourly basis, so for those in need of a quick test, godaddy cannot do that according to their own site. I don't recall if anyone posted that in here or I only came across it in other sites, so I thought I would pass it along.

thanks again,
