This would be the best, but unfortunately, our product information system does not keep "last modified" on the product path, much less a history of what values used to be. I just don't have data available to create this map. ===another solution=== I have thought of another solution that avoids the rewrite program. I could make a rewrite map that contains every valid product URL and maps it to 1. e.g. /etc/httpd/good_product_urls.txt /product/New_Path_To_Product1?sku=000001 1 Then add a rule like: RewriteMap good_product_urls txt:/etc/httpd/good_product_urls.txt # skip product path rewriting if the URL is already correct RewriteCond %{REQUEST_URI} ^/product RewriteCond ${good_product_urls:%{REQUEST_URI}?%{QUERY_STRING}} 1 RewriteRule ^ - [S=1] ...Rule for product path rewrite --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
