Mojolicious::Plugin::AssetPack::Manual::CustomDomain - How to serve assets from a different host


You might want to serve the assets from a domain different from where the main app is running. The reasons for that might be:

  • No cookies send on each request. This is especially useful when you use Mojolicious sessions as they are stored in cookies and clients send whole session with every request.

  • More requests done in parallel. Browsers have limits for sending parallel request to one domain. With separate domain static files can be loaded in parallel.

  • Serve files directly (by absolute url) from CDN (or Amazon S3).


To use the feature, just set a custom "base_url":

  plugin "AssetPack" => {
    base_url => ""

Many recent browsers blocks mixed content, meaning if your HTML is served over HTTPS, then you can't serve the assets over HTTP. One way to fix this is by using "//" instead of a scheme specific URL. Example:

  base_url => "//"

This will tell the browser to use the same scheme for fetching assets, as it did fetching the web page.
