Remarks

The following examples demonstrate the effect of combining a base URI and a relative URI. Note that the first example ends in a resource, and the second example ends in a path segment.


BASE:      http://www.adatum.com/abc/def
RELATIVE:  xyz
COMBINED:  http://www.adatum.com/abc/xyz

BASE:      http://www.contoso.com/abc/def/
RELATIVE:  ../../default.htm
COMBINED:  http://www.contoso.com/default.htm

For more information on the algorithm used to combine a base URI and a relative URI, refer to RFC-3986 Section 5.2, "Relative Resolution."
