No .htaccess is needed.

Note that the escaped_fragment has also been removed. See https://webmasters.googleblog.com/2015/10/deprecating-our-ajax-crawling-scheme.html.

It fixes a "double slashes" issue, which happened when using config from official Prerender.io docs (e.g. it crawled and logged http://example.com//favicon.ico).

This is for Apache 2.4 only.
