Greetings

I guess I am not sure what is happening when I enable spider-friendly URLs for the forum. What exactly is making these pages spider-friendly? There are no meta tags being created within the html code (which most if not all major spiders utilize to index/list site pages), though i do see a <title> tag with "forum name: topic name". Is the presence of the title what we mean by spider friendly?

Also, regarding the "fake" html extension, how is this being written in the browser's (and spider's) address bar? I see that no actual html file exists, so the fake html extension must be rendered each time the page is called. I am wondering whether there is significant processor overhead if I add this extra rendering process for each page load.

thanks much
