Welcome to the Q&A Forum

I would have to agree with you there. Most of these content farms have been dropped by google. You can waste alot of time writing pages when in my opinion, time is better spend optimising the content and quality of your own page and perhaps focus on getting back links from higher quality sites.

I had a similar problem and found this site particuarly useful: http://httpd.apache.org/docs/2.0/misc/rewriteguide.html

Works great for me now. Good Luck.
