Interface ResourceEngine
-
public interface ResourceEngine
TheResourceEngine
is used to create implementations of theResource
interface that suit the targeted resource. DifferentResource
objects may be needed to handle different files/directories or even applications. The request URI specified must be a HTTP request URI as of RFC 2616.The meaning of HTTP URI in this instance is the request URI from a HTTP/x.x request, as RFC 2616 and RFC 2396 defines it
Request-Line = Method SP Request-URI SP HTTP-Version CRLF Request-URI = "*" | absoluteURI | abs_path | authority absoluteURI = "http:" "//" host [":" port] [abs_path ["?" query]] abs_path = "/" path_segments path_segments = segment *( "/" segment )
TheResourceEngine
object must be prepared to accept the request URI that come in the form outlined above. These can include formats likehttp://some.host/pub;param=value/bin/index.html?name=value http://some.host:8080/index.en_US.html some.host:8080/index.html /usr/bin;param=value/README.txt /usr/bin/compress.tar.gz
TheResourceEngine
implementation should be able to directly take a Request-URI as defined in RFC 2616 and translate this into aResource
. This keeps the objects semantics simple and explicit, although at the expense of performance.- Author:
