 NOTE: Recall that in URLs, characters that fall outside the ASCII character set are encoded. For example, a space is encoded as %20 and the dollar sign ($) is encoded as %24. When specifying variable names found in a URL, use the encoded value for these characters. For a list of encodings, see http://www.w3schools.com/TAGS/ref_urlencode.asp.  |
