URL can be categorized into Absolute URL and Relative URL.
Absolute URL: Absolute URLs are the URLs with a complete internet address specifying the location of a
resource. An Absolute URL includes protocol, host, path and name of the resource.
For example : www.thetouchpad.com/index.htm.
Relative URL: A relative URL is not fully complete but it inherits the protocol, host and path information from
its parent document (the document file that links to it). Relative UR s are used to refer to links on the same
server as the page that contains them.
Most of the web pages are identified by relative UR where hyperlinks point to (last destination) documents
and other files which are located on the same site. eg. link.htm.
