DNS Redirect sub domains, top level domains, and folder structure jacatching[ at ]comcast.net 10/20/2008 5:26:28 PM I am not a systems engineer. However, I have been tasked to conduct some research, so please be patient with my lack of knowledge of DNS servers and the way they work. 1. We have an internal(intranet) webserver shared by several departments 2. My department owns several applications that sit on the shared web server. 3. The company wants to eventually EOL the existing server including the subdomain and have a dedicated server for each department. 4. We must move our apps to our new server NOW - several months before the planned EOL - and do it without breaking existing links on the intranet that link into our apps. e.g. http://alldepartments.company.com/mydepartement/news.aspx?article=1 My understanding is that it is impossible to redirect HTTP requests at the DNS level using folders i.e. http://alldepartments.company.com/mydepartement/news.aspx?article=1 and redirect the request to http://mydepartment.company.com/newsgroup/news.aspx?article=1 So, my question: Is it possible to redirect at the DNS level the top level domain and sub domain portion? Meaning, can an HTTP request of http://alldepartments.company.com/ be redirected to http://mydepartment.company.com If so, by migrating the app to the new server and keeping the folder structure the same wouldn't it maintain the integrity of the links and resolve the HTTP requests to the new server? Example: http://alldepartments.company.com/mydepartement/news.aspx?article=1 and redirect the request to http://mydepartment.company.com//mydepartement/news.aspx?article=1 Unfortunately, the departments have to migrate the apps in stages and therefore we are all running into this problem. Any suggestions or comments are welcomed and appreciated. Thanks in advance.

I'm guessing though that you have multiple pages here and a redirect is probably not possible. There is probably some html trick to do this but this really is outside of the scope of this DNS newsgroup and would suggest you repost (Cross post) in a web development Newsgroup. -- Paul Bergson MVP - Directory Services MCTS, MCT, MCSE, MCSA, Security+, BS CSci 2008, 2003, 2000 (Early Achiever), NT4 http://www.pbbergs.com Please no e-mails, any questions should be posted in the NewsGroup This posting is provided "AS IS" with no warranties, and confers no rights.
