Permalink variables OR two pages – Please help !

Hi,

I want to show a description page template before showing every posts in my blog. (a pre-post page that have “read more” link)

my site permalinks are set like this.

http://www.website.com/242/articles/news/post-name.html

So how can I parse a variable to that permalink ?
for example :
http://www.website.com/242/articles/news/view-post-name.html

so I can use if conditions to show the first page and then the user clicks on “Read More” link and the second page will load using PHP.

Thanks.
