Possible mirroring!

Looking for a solution to Web site-database mirroring? 5 geographic sites w/ wan connectivity but slow. I was looking at 3rd party software to “mirror” my web site and a “cached” version of our database. Has anyone done this successfully nad or what softawre? I am wondering about simply inserting the website “folder” in a DFS folder. The web folder ad cached database folder is in one folder. There probably is a better way to go but I was wondering if anyone has tried this yet?
Our reason. 5 sites….. very slow links. Each site is OK to work on their own for several hours.
This is a W3k AD single domain private farme relay sites.
