Resolve a URL reference against this base URL.
result< void > resolve( url_view_base const& ref);
This function attempts to resolve a URL reference
against this base URL in a manner similar to that of a web browser resolving
an anchor tag. This URL must satisfy the URI grammar.
In other words, it must contain a scheme. Relative references are only
usable when in the context of a base absolute URI. This process of resolving
a relative reference within the context of a base
URI is defined in detail in rfc3986 (see below). The resolution process
works as if the relative reference is appended to the base URI and the
result is normalized. Given the input base URL, this function resolves
the relative reference as if performing the following steps:
url base1( "/one/two/three" ); base1.resolve("four"); assert( base1.buffer() == "/one/two/four" ); url base2( "http://example.com/" ) base2.resolve("/one"); assert( base2.buffer() == "http://example.com/one" ); url base3( "http://example.com/one" ); base3.resolve("/two"); assert( base3.buffer() == "http://example.com/two" ); url base4( "http://a/b/c/d;p?q" ); base4.resolve("g#s"); assert( base4.buffer() == "http://a/b/c/g#s" );
