for the past months, googleBot has been hitting a file that does not exist anymore on my site [index.php] as all the routing to the proper home pages in the proper languages is handled via apache rewrite rules in the htaccess.

Ans to, I commented out my .htaccess the DirectoryIndex index.php rule

RewriteEngine on
RewriteBase /
Options +FollowSymLinks -Indexes -ExecCGI
# DirectoryIndex index.php    (not needed anymore, index.php doesnt exist)
# DirectoryIndex /en/home     (should it be set to this 开发者_运维技巧now??)

Currently, Everything works sublime: the http://website.org root is redirected instantly to /en/home via 301 permanent rediret!

But

66.249.67.142 / == crawl-66-249-67-142.googlebot.com is hitting my site again and again trying to read index.php, which does not exist. What should I do??

A sneak peak into the endless error log file with such entries (poor googlebot i thought it might be more intelligent...)

Someone linked to index.php, so Google is trying to follow it.

Do a rewrite from index.php to /en/home, and you'll be golden.

E: Also, DirectoryIndex can't be a Path, AFAIK. It just tells the server which file in a directory should be served if not specified otherwise.

/ and /index.php are separate resources as far as anything accessing your site through HTTP is concerned. Just because you are redirecting /, it doesn't mean anything if Google has seen links to /index.php before.

Just redirect /index.php to /en/home in the same way as you are redirecting /.
