I stole that title from this gizmodo article. I suggest you read the comments before you read the article itself. I did and went on to look for something possibly more authoritative. Here are two:
- W3C: URI_Recommentations.html. “The World Wide Web Consortium (W3C) is an international community where Member organizations, a full-time staff, and the public work together to develop Web standards.”[About W3C]
- Google: Dynamic URLs vs. static URLs.
For more “Official news on crawling and indexing sites for the Google index”, go to Google’s Webmaster Central Blog.
If you want even more information, you might search for something along the lines of [how to read OR parse a url].
If you want to try reading/parsing a url on your own, here’s one to try. Note that it’s >1600 characters long.
