Cookies and URL questions

1

I have two questions and not sure where they should be posted, but I thought this would be the best place.

  1. I am making a site that has a flash intro that explains about the company… Is there a way to have a cookie stored on the person’s computer so that when they come back to the site it skips the flash intro they already viewed… for instance if the flash intro is on index.html it would forward them to the site on index2.html

  2. how do some sites hide the trailing end of their URls… instead of it displaying like:

http://www.mydomain.com/index.html, contact.html, etc.

it would just display as:

http://www.mydomain.com/

Thanks for any advice you can give on this.
