Authorizing and Mapping Urls and Domains
pagespeed Domain http://example.com
pagespeed Domain cdn.example.com
pagespeed Domain http://styles.example.com/css
pagespeed Domain *.example.org
PageSpeed will rewrite resources found from these explicitly listed domains, although in the case of
styles.example.com only resources under the
css directory will be rewritten. Additionally, it will rewrite resources that are served from the same domain as the HTML file, or are specified as a path relative to the HTML. When resources are rewritten, their domain and path are not changed. However, the leaf name is changed to encode rewriting information that can be used to identify and serve the optimized resource.
The leading "http://" is optional; bare hostnames will be interpreted as referring to HTTP. Wildcards can be used in the domain.
These directives can be used in location-specific configuration sections.
