ASP help needed...please see

Can anyone please solve my this problem in ASP
I have say a ASP site
eg. www.mysite.com
I go to some link
and reach
www.mysite.com/headlines
Now there are many news on this page
I click on one headline and I get it to the news page
with the url of the page like
http://www.mysite.com/news/details.asp?id=255&pageno=1
Actuall this is a page retrived through the query passed to database
What is want is that the url which is shown in the browser should be html
rather like asp
Something like www.mysite.com/news/dir/0001.html with 0001.html being the
oldest new etc
How do I do it
If anyone can do it would be greatful for me
I am willing to pay too

Thanks
