Hi, I am hoping to build a rails app that can create other rails apps and run them. Basically the user fills in some parameters and a new rails app is generated. Once generated, then the new application is running. I have no problem putting together the code that generates the new app. However, I am having trouble with figuring out how to run the new applications. I see two main options: 1. Reconfigure my web server to support the new app. This is not my preference because I would not like to change my code to support different hosting environments (development/production). 2. Having my main rails app accept all the requests, then send them on to the new app. I really don’t know how this would work. Is it possible? Is it reasonable? All of the apps will be low-traffic. Thanks! ---

If it low traffic why not install it on subdomain on the same host? [Http://www.rubyplus.org](Http://www.rubyplus.org) Free Ruby & Rails screencasts ---

Thanks for the reply! I am hoping to use the same host. However, I want the entire application to be set up programmatically. I know I could just reconfigure the webserver, but I would really like to keep my implementation webserver agnostic (if possible). As for subdomains, they would certainly look very nice. However, I don’t know if this will be possible without making my implementation webserver-specific. Please let me know if I am wrong! Cheers ---

Check out adv rails recipes. It shows how to use subdomains in rails apps. [Http://www.rubyplus.org](Http://www.rubyplus.org) Free Ruby & Rails screencasts ---

Advanced Rails Recipes has been on my wish list since Christmas, but Amazon isn’t shipping it to Canada yet ☹ I did check out this page [http://wiki.rubyonrails.org/rails/pages/HowToUseSubdomainsAsAccountKeys](http://wiki.rubyonrails.org/rails/pages/HowToUseSubdomainsAsAccountKeys) That was kind of useful, but it doesn’t really address the whole issue. I need these to be completely separate rails apps. Each one gets its own database, etc. Thanks!
