In our application we do url rewrite for all the pages. For example you have . Recently we changed all the urls to be /adults/about/ or /kids/about/ ... Now all the previous urls like "/about/" will give 404. Is there a way to add 301 redirect and force all the pages like "/about/" to go to "/adults/about/". I found a way but I am not sure it is a good one or it will help in SEO. What I did is added a url rewrite for the "/about/" like the "/adults/about/" and then in the page_Load checked if there is no "adults" or "kids" in the url then redirect to "/adults/about/". The adults and kids are not folders. They just help in differentiating the nav menu.
Sorry if the title is not clear.
