#### Installing Web Applications in Ruby

You can install on your site custom Web applications developed in the Ruby programming language.

To install on your site an application written in Ruby:

1. Go to Domains > Domain name > Setup.
2. Select the CGI and FastCGI check boxes, and click OK.
3. Connect to your FTP account, change to the `/htdocs` directory, and create a subdirectory where the application files will reside. Let's call this directory `your_application`, for illustration purposes.
4. Upload the application files to the `htdocs/your_application` directory.
5. Create a file with name `.htaccess` in this directory, open it with a text editor of your choice and add the following lines into the file:

   `RewriteEngine On RewriteRule ^$ /public/index.html [L] RewriteCond %{REQUEST_URI} !^/your_application/public`

   `RewriteRule ^(.*)$ /public/$1 [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ public/dispatch.fcgi/$1 [QSA,L]`

6. Save the file.
7. Remove the file `your_application/public/.htaccess`
8. Open the file `your_application/public/dispatch.fcgi` with a text editor and put the following lines there: `#!/usr/bin/ruby`
9. Save the file.

Now the web application will be accessible at the following URL: http://your-domain.com/your_application.
