Recently I had a client who had his entire website remade by an outside designer. His old site had very good search engine placement, so he insisted that the designer use the exact same file names for every html file. The designer followed the spec was was not concerned about case sensitivity. So something the old site that may have read “www.mysite.com/Free-Beer.html” the designer made it “www.mysite.com/free-beer.html”.

I was tasked with changing this, but was in no mood to rename all files, especially since the its probably better to keep everything lowercase and goggle would re-index anyway.
A quick google lead me to joebert’s post on digitalpoint forum. He provided this htaccess rule to convert all uppercase letters in the url to lowercase. Works great and my client is happy.

thanks joebert
