Multiple 301 Redirect For Multiple Pages or URL

问题

I am redesigning my store and so the old structure has been changed with the new structure. So trying to redirect all old products with the new.

I have more than 20-25 products and if I write redirect rule for every product than I have to write in this way

Redirect 301 /store/products/somename/ http://store.domain.com/nicecar
Redirect 301 /store/products/blabla/ http://store.domain.com/newpros
Redirect 301 /store/products/cubacuba/ http://store.domain.com/illollo

Which will become to long and may slow down the site. So is there anyway to optimize this redirect rule?

Thanks a lot

It is better to use RewriteMap for your requirement. Here is an example how to use it:

1. Add following line to your httpd.conf file:

   RewriteMap prodMap txt://path/to/prodMap.txt
   

2. Create a text file as /path/to/prodMap.txt like this:

   somename nicecar
   blabla newpros
   

3. Add these line in your .htaccess file under DOCUMENT_ROOT:

   Options +FollowSymLinks -MultiViews
   RewriteEngine on
   
   RewriteRule ^store/products/([^/]+)/?$ http://store.domain.com/${prodMap:$1} [L,R=301,NC]

If you have access to the vhost or server config, you can setup a rewrite map, though in reality, it's probably marginally faster than just having a ton of redirects. The redirects that you have in your htaccess file are cached, so as long as the htaccess file isn't modified, the directives don't need to be re-read.

There's a very detailed tutorial for how to use RewriteMap and the many various mappings you can use with it.
