I ended up donating 9e to the developer, just to say thanks.
Used on an e-commerce site to great effect!
Needed to keep my search page position for items that have been replaced by different ones with different urls. Did not want the dreaded 404 to lose me site position.
ReDJ is the perfect solution for the job!
When I changed a range of items it was simple to use the pattern matching to create one redirect that sent all possible urls from a range to the new page - saved me hours of work.
Make sure you read the tutorial/documentation and you will see how powerful this plugin really can be if you need it to be.
A query I had was answered so quickly be the developer - another massive positive for this product.
Oh, and don't miss the ability to define a custom 404 page in multi language.
