This is tricky in many ways, because you can inadvertently create infinite duplicate content. If you discard the content of $1, $2 and $3, and only use the number in $4 as a key to pull the record from the database, I could link to www.example.com/useless_junk_product_26.html and the same page would display. You really do need to take the other parts and validate them against the real article title as stored in the database - and then either send a 404 Not Found page, or redirect the user to the correct URL for that content. RewriteRule cannot see the leading / on a URL request. That's the main reason your rule does not work. Be aware that your rule will also respond to both www and non-www requests unless you take action to redirect all non-www URL requests over to the www version of the URL. This redirect must go before the rewrite in the .htaccess file.

Could I get all the values and than check them using php? [___.com...] [___.com...] RewriteEngine On
RewriteRule ^/([0-9]+)_([a-z]+)_([a-z]+)_([0-9]+).html$ /vehicle.php?id=$4&year=$1&make=$2&model=$3 <?php some php code that checks to see if the year, make and model match the actual values for the id ?> [edited by: matthewamzn at 7:36 pm (utc) on Mar. 25, 2009]

Yes, that is exactly what you need to do. Whether you then send HEADER 301 or HEADER 404 is up to you.

'RewriteRule cannot see the leading / on a URL request. That's the main reason your rule does not work.' Do I need to make it see it or put something in it's place?

... Or take it out of your pattern. :) There's no leading slash on what your pattern is attempting to match against.

ok thanks, this is working now: RewriteEngine On
RewriteRule ^([0-9]+)_([a-z]+)_([a-z]+)_([0-9]+).html$ /vehicle.php?id=$4&year=$1&make=$2&model=$3

Don't forget that extra non-www to www 301 redirect ahead of your rewrite!

Is that important for seo? I looked it up. Do you mean something like this? RewriteEngine On
RewriteCond %{HTTP_HOST} ^_______\.com [NC]
RewriteRule ^(.*) [_______.com...] [R=301,L]
RewriteRule ^([0-9]+)_([a-z]+)_([a-z]+)_([0-9]+).html$ /vehicle.php?id=$4&year=$1&make=$2&model=$3

Yes, that's one version of it. Yes it is important, otherwise every page of your website ends up with two Duplicate URLs.

Escape all literal periods in patterns as shown, and add an [L] flag to your rewrite:
RewriteEngine On
#
RewriteCond %{HTTP_HOST} ^example\.com [NC]
RewriteRule ^(.*)$ http://www.example.com/$1 [R=301,L]
#
RewriteRule ^([0-9]+)_([a-z]+)_([a-z]+)_([0-9]+)\.html$ /vehicle.php?id=$4&year=$1&make=$2&model=$3 [L]

I'm having one problem with it. It's removing the directories if www. isn't included. _____.com/path/page.php becomes [_____.com...] Shouldn't the * tell it to append the entire path? RewriteEngine On
RewriteCond %{HTTP_HOST} ^_____.com [NC]
RewriteRule ^(.*)$ [_____.com...] [R=301,L]
RewriteRule ^([0-9]+)_([a-z]+)_([a-z]+)_([0-9]+).html$ /vehicle.php?id=$4&year=$1&make=$2&model=$3

Yes, (.*) matches the entire URL-path into the local variable $1, so it is re-inserted in the substitution URL. Be sure you completely flush your browser cache after changing any server-side code. Jim

Thanks Jim, it's working well now.

You need [L] on the end of the final rewrite line.

And the other changes/improvements, as posted above... Jim
