Duplicate Content From Indexing of non- File Extension Page

[TakeshiYoung]

You repeat this code a few times, maybe that's the problem? Pretty sure you only need it once:

RewriteEngine On
Options +FollowSymlinks
RewriteBase /

The line:

RewriteEngine On

Also only needs to be included once in an htaccess file. You may want to remove all the other instances.

Try adding this code at the very top, after the first "RewriteEngine On":

RewriteCond %{REQUEST_URI} ! .html$
RewriteCond %{REQUEST_URI} ! /$
RewriteRule ^(.*)$ $1.html

I get a server error when I do this?  Sooo confused...  Here is the htaccess changes I made.  FYI...I have removed the code you told me to put in there temporarily so the site's not down.  I attached the server error screenshot too...

Options +FollowSymlinks
RewriteEngine On

RewriteCond %{REQUEST_URI} ! .html$
RewriteCond %{REQUEST_URI} ! /$
RewriteRule ^(.*)$ $1.html

RewriteCond %{HTTP_HOST} ^hanneganconstructionllc.com [NC]
RewriteRule ^(.*)$ http://hanneganremodeling.com/$1 [L,R=301]

RewriteCond %{HTTP_HOST} ^www.hanneganconstructionllc.com [NC]
RewriteRule ^(.*)$ http://hanneganremodeling.com/$1 [L,R=301]

RewriteCond %{HTTP_HOST} ^hremodeling.com [NC]
RewriteRule ^(.*)$ http://hanneganremodeling.com/$1 [L,R=301]

RewriteCond %{HTTP_HOST} ^www.hremodeling.com [NC]
RewriteRule ^(.*)$ http://hanneganremodeling.com/$1 [L,R=301]

RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /index.html\ HTTP/
RewriteRule ^index.html$ http://www.hanneganremodeling.com/ [R=301,L]

RewriteBase /
RewriteCond %{HTTP_HOST} ^hanneganremodeling.com$ [NC]
RewriteRule ^(.*)$ http://www.hanneganremodeling.com/$1 [R=301,L]

Maybe give this a whirl:

If URL does not contain a period or end with a slash

RewriteCond %{REQUEST_URI} !(.|/$)

append .html to requested URL

RewriteRule (.*) /$1.html [L]

[WebbyNabler]

Nope.  Didn't work.  I am seriously about to lose my mind with this....

[WebbyNabler]

Oh, and my site auditor is seeing it as a directory with a file in it???  Ugghhh....

[TakeshiYoung]

Try my code without all the other redirects, and see if it works. If it does, then add back the other redirects one by one until everything works.

[WebbyNabler]

That caused the same "500 Internal Server Error" .......  

[TakeshiYoung]

Try:

RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^.]*[^./])$ /$1.html [R=301,L]

[Mike.Goracke]

If that does not work, give this a whirl:

RewriteCond %{REQUEST_URI} !\.[a-zA-Z0-9]{3,4}

RewriteCond %{REQUEST_URI} !/$

RewriteRule ^(.*)$ $1.html

[WebbyNabler]

Nope.

[WebbyNabler]

Nope. .....good lord....

[Mike.Goracke]

LAME! You may just want to let the 301 redirect you have in place take its course or remove the URL from Google's index since it was added by mistake anyway.

Yeah I looked further into the URL removal, but I guess technically I did not meet the criteria....and honestly I am fearful other potential implications of removal....I guess I will just have to wait for the 301 to ick in.  I just cant believe there is not a simple .htaccess code to cause all URL's to show the .html extension.  I mean it is a simple thing to implement the reverse and have the extension dropped...I mean....good lord...

Thanks for all your help though Mike, I truly appreciate the efforts!
