Static (seo friendly) to dynamic url rewrite

Question

Here is my problem...

I have a to redirect a link like this:

site.com/virtualfolder/some-seo-friendly-keywork
to
site.com/folder/page.php?id=some-seo-friendly-keyword

In site.com there is no real folder "virtualfolder", it is virtual. I have to take "some-seo-friendly-keyword" and use it as a query string

I think i have to firts match the folder "virtualfolder" and then capture the "some-seo-friendly-keyword", but how? The some-seo-friendly-keyword is a string of characters and digits plus hypens so something like this below is realistic?

RewriteRule ^virtualfolder/([a-zA-Z0-9-])? folder/page.php?id=$1 [L]

I'm still strudying and trying mod_rewrite and it is like voodoo to me! :-/

Thank you very much for your help or your suggestions

Try with this code in htaccess:

Using the original url to show:

Rewriterule ^virtualfolder/([a-zA-Z0-9_-]+)$ folder/page.php?id=$1

Redirecting to end url using RedirectMatch (use the full URL in the second part):

RedirectMatch 301 ^/virtualfolder/([a-zA-Z0-9_-]+)$ http://www.site.com/folder/page.php?id=$1

Redirecting to end url using mod_rewrite (use the full URL in the second part):

Rewriterule ^virtualfolder/([a-zA-Z0-9_-]+)$ http://www.site.com/folder/page.php?id=$1 [R=301,L,NE]
