The dream of every person starting out to build websites is to reach out to as many people as possible. Not very many actually make it to more than a few hundred visitors per month on a regular basis. But with the profusion of social bookmarking sites, there is a chance for some of these low traffic sites to get bursts of very high traffic once in a while, for ex: when they get slashdotted. The question is how to outlive such spikes in traffic, without burning large holes in your pocket

When things don't work the way you want it to and all it takes is a hack in the core, people sometimes hack the core.

Most webmasters do not realize this, but a lot of the content on lot of websites can be accessed from multiple URLs. A simple example would be where www.example.com and example.com leads to the same page. This is a fatal mistake in Search Engine Optimization and search engines penalize you for duplicate content. The correct configuration would be where the above two urls will lead you to the same page but example.com will redirect you to www.example.com with a 301 (Moved permanently) status which will not result in search engines penalizing the page. It is very easy to configure 301 redirects using Apache .htaccess file and the process is the same for a Drupal installation also.
