@sanket,

Converting relative URLs to absolute is necessary, but, I was referring to canonicalization of URLs — different URLs can be referring to the same resource. For example, http://www.grok.in:80/ and http://www.grok.in/ refer to the same resource. Canonicalizing URLs will ensure that these different URLs are considered as the same; in the previous example, both the URLs will be normalized to one of the two forms.

What is *URL Normalization*? Converting relative to absolute addresses or something like that?

good to know you write crawlers. I was doing research in Grid Computing sometime back when I dived into crawlers and fell in love with the whole concept and the math involved, is a field to spend a lifetime in. Good post.
