# symbol in URL - what does this mean?

[eluser]Nick Husher[/eluser]
The # character is used to signal the browser to center the view on a particular named element.

So a link to www.example.com/#my-content will center on an element with an id of "my-content"

Many obtrusive javascript libraries will insert links like <a href="#"click="...">Javascript Link</a>, hence your mystery # at the end of the uri string. Note that anything that comes after the # will not be passed to the server through GET parameters.
