[CONTRIBUTION] Ultimate SEO URLs v2.1 - by Chemo in General Add-Ons Support Posted March 20, 2010 Does anyone have a recommendation on how to deal with the problem of inserting 301 redirects on an old site to transition to Ultimate SEO? I have version Ultimate_SEO_URLSv22d_7 installed on a new site and it is working great and now want to install it on an existing site, but my seo guy says I need to redirect all the old product URL's. I found this post referencing Ultimate SEO which suggests dynamically rewriting page requests that use the old format: About half way down this page is a discussion by Gtech: http://forums.digitalpoint.com/showthread.php?t=136032 Seach the page for the "1) Ultimate SEO is what you want. This is a great contribution and I use it myself." to jump right to it. But I wanted a second opinion from this forum. What's the best solution to the 301 problem for a user of Ultimate SEO on an established osCommerce site?
