htaccess Redirect 301 problem .. all redirects with one string fail to redirect and 404

So I have moved a website and am trying to 301 redirect everything, which I do quite often so this is a weird problem but probably something stupid I'm not seeing.

ALL of my redirects are working fine, except any redirect that the first string starts with "/Dining" or "/dining" are failing. For example, this redirect works fine-

Redirect 301 /healthfitness/teeth.cfm /healthcare/pretty-teeth

...as well as 100s of others.

But all of these are failing (many more than I'm showing)-

Redirect 301 /Dining/diningreviews/vawines.cfm /shopping/wines-2004
Redirect 301 /Dining/diningathome/carrotcake.cfm /home-garden/carrot-cake-2003
Redirect 301 /Dining/diningathome/oldvarolls.cfm /home-garden/virginia-rolls-2003
Redirect 301 /Dining/diningathome/pumpkincake.cfm /home-garden/pumpki开发者_高级运维n-cake-2003

The top of my .htaccess file looks like this-

RewriteEngine On
RewriteBase /

#uploaded files
RewriteRule ^(.*/)?files/$ index.php [L]
RewriteCond %{REQUEST_URI} !.*wp-content/plugins.*
RewriteRule ^(.*/)?files/(.*) wp-content/blogs.php?file=$2 [L]

# add a trailing slash to /wp-admin
RewriteCond %{REQUEST_URI} ^.*/wp-admin$
RewriteRule ^(.+)$ $1/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule . - [L]
RewriteRule  ^([_0-9a-zA-Z-]+/)?(wp-.*) $2 [L]
RewriteRule  ^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L]
RewriteRule . index.php [L]

<IfModule mod_security.c>
<Files async-upload.php>
SecFilterEngine Off
SecFilterScanPOST Off
</Files>
</IfModule>

#Everything below here are Redirect 301s

Dont redirect statements have to include the protocol in the destination?

You must include the domain name in the redirect.

Never mix mod_alias and mod_rewrite directives in the same file. If you use RewriteRule for any of your rules, you must use RewriteRule (not Redirect or RedirectMatch) for ALL of your rules.

List all redirects (using RewriteRule syntax) before any of the rewrites (using RewriteRule syntax) otherwise you will inadvertently expose rewritten pointers back out on the the web as new URLs.

The code you are currently using is very very inefficient. The .* patterns mean your .htaccess file will attempt hundreds of thousands of "back off and retry" trial matches for every URL request hitting the server.

In particular,

^(.\*/)? should be replaced by ^([^/]+/)\* in two places.

^.\*/ should be replaced by ^/([^/]+/)\*

!.\*wp-content/plugins.\* should be replaced by !wp-content/plugins

^([_0-9a-zA-Z-]+/)?(.\*\\.php)$ should be replaced by ^([_0-9A-Z-]+/)?([^.]+\\.php)$ with the [NC] flag also added.

The "add a trailing slash to /wp-admin" redirect should be the very first ruleset in the file and the target URL should include the protocol and domain name. That rule should be immediately followed with a non-www to www canonicalisation rule.

The new code may well run hundreds of times quicker.
