This demo shows how you can use Pirsch on your website using JavaScript to create roll-up views.
Adjust the snippets in static/index.html and static/page.html with your identification code, the URL, and remove the data-*-endpoint attributes.
Create a dashboard for bar.com and add foo.com as an additional domain.
Use any HTTP server you like to serve the bar.com and foo.com directories. Here is an example using PHP on bar.com and foo.com. Edit your hosts file to create a loop back for the two domains so that they point to localhost.
cd demo/rollup/bar.com
php -S bar.com:8081In a second terminal:
cd demo/rollup/foo.com/dir
php -S foo.com:8082Open bar.com:8081 in your browser.
