Enabling HTTP Compression for JS and CSS File Loading

You can improve your load times for JavaScript and CSS file loading if you enable HTTP compression for IIS.

To enable HTTP compression

  1. Navigate to the Setup section of Microsoft's HTTP Compression doc.
  2. Find and follow the steps for setting up HTTP compression for your server version
  3. Microsoft says that the default install of IIS 7 or later enables static compression by default. Double-check that this happened as expected.
