Yahoo Slurp Adds Wildcard Support For Robots.txt

The Yahoo Search Blog announced that Yahoo's web crawler, aka Yahoo Slurp, now supports wildcards in the robots.txt file. The two parameters that Yahoo now supports include the "*" and the "$." The * will tell Yahoo to do a "wildcard match a sequence of characters in your URL." The & will tell Yahoo to do a "anchor the match to the end of the URL string."
