Question

http://www.example.com?foo

What\'s the term for the foo part of the URL?

Answer 1

Depends on the technology you use. Usually its called name value pair. Query string refers to the whole string after ? sign. Then depending on technology used that query string is parsed and normally appears as the dictionary. For example, http://www.example.com?foo=bar&foo1=bar1: Request["foo"] yields "bar" Request["foo1"] yields "bar1" for asp or $_GET["foo"] -> "bar" for php and so on.

Answer 2

Its the query, or sometimes the query string.

To pinch a useful diagram from the URI RFC:

     foo://example.com:8042/over/there?name=ferret#nose
     \_/   \______________/\_________/ \_________/ \__/
      |           |            |            |        |
   scheme     authority       path        query   fragment

Answer 3
