We've had requests from clients via their SEO companies to host blogs accompanying ecommerce sites on
theirdomain.com/blog rather than on - for example -
As we look after their ecommerce hosting, and don't host wordpress sites (These are hosted on wpengine.com), we've had a few requests to accomplish this using
ProxyPass which allows us to forward all requests on a virtual subfolder to a different domain. Example setup below:
Redirect /blog /blog/ ProxyPass /blog/ http://blog.theirdomain.com/ ProxyPassReverse /blog/ http://blog.theirdomain.com/ ProxyPassReverseCookieDomain blog.theirdomain.com www.theirdomain.com ProxyPassReverseCookiePath / /blog/
This means each request to
theirdomain.com/blog is forwarded to their blog on a subdomain. Apparently it's preferential for Google to have your blog hosted this way. However, it seems to me that any advantage you'd have from this (assuming there is an advantage) would be eradicated by the latency introduced on every single request to your blog, or an asset on your blog, in the fact that every single request has to be redirected via our server.
Is there any evidence to support either perspective on this?
