Hi Guys, I would like to ask about help. There is following things I need to ask. I am working on website for my client but the previous one had a special function of URL rewriting. See below: 1. My client had a website with Search Engine Friendly URLs 2. This website has example structure: domain.com/example-page.html domain.com/example-page2.html domain.com/John-Smith.html 3. As you see sometimes there are capital letters in file names 4. When you trting to change any letter in filenames there is 301 redirection to earlier defined version of URL for example: domain.com/eXamPle-page.html > Redirection 301 > domain.com/example-page.html domain.com/John-Smith.html > Redirection 301 > domain.com/john-smith.html That means its impossible to make duplicate content. NOW: I want to know how they done this. How the previous web design company wrote this. Where the URL case definitions are stored and how to make this for other websites. Please help...
