410 error with htaccess for all *.html pages in Joomla?

[Aiden]

Recently, I had a problem with my web server. Having a security hole at Joomla, somebody created thousands of files (ending in *.html) in my website.

I have removed all these files, but Google keep querying this particular files. I have previously added a more than hundred of pages at Google Webmaster Tools being removed, however there are still lots of files.

I just want to put a rule in the .htaccess file to return a 410 error code when any file ending with .html is requested, EXCEPT if the page is googlea1b2c3d4e5f6.html (a file from google).

How to sort out this problem?

You can add the following rule in htaccess:

RewriteEngine on

#--exclude "/googlea1b2c3d4e5f6.html--#
RewriteCond %{REQUEST_URI} !^/googlea1b2c3d4e5f6\.html$ [NC]
#--redirect all .html requests to 410 Gone--#
RewriteRule \.html$ - [R=410,L]
