It is cumbersome to use a full, absolute URI for every reference to a resource. Consequently, you can use a relative URI in many locations.
For example, a document located at “
http://www.nmt.edu/” may refer to another
document located at “
using that absolute URL. Alternately, it may use the
relative URL “
A relative URI must always be evaluated in the context of
an absolute base URI. In the
example above, the relative URI is evaluated in the
context of the base URI “
For complete details of URIs and the process of converting a relative URI to absolute form, see RFC 3986: Uniform Resource Identifier (URI): Generic Syntax.
