Changes in this pull request

I tried the setup instructions but did not get static files to be served. Not sure if the original configuration would be the correct one for some versions of Apache (its been quite a while since i had to use it), but with my 2.4.57, the REQUEST_FILENAME is only the path and we need to prepend the DOCUMENT_ROOT
