/**
|
|
* URIs are essentially structured names for things -- anything. This interface
|
|
* provides accessors to set and query the most basic components of an URI.
|
|
* Subclasses, including nsIURL, impose greater structure on the URI.
|
|
*
|
|
* This interface follows Tim Berners-Lee's URI spec (RFC2396) [1], where the
|
|
* basic URI components are defined as such:
|
|
* <pre>
|
|
* ftp://username:password@hostname:portnumber/pathname#ref
|
|
* \ / \ / \ / \ /\ \ /
|
|
* - --------------- ------ -------- | -
|
|
* | | | | | |
|
|
* | | | | | Ref
|
|
* | | | Port \ /
|
|
* | | Host / --------
|
|
* | UserPass / |
|
|
* Scheme / Path
|
|
* \ /
|
|
* --------------------------------
|
|
* |
|
|
* PrePath
|
|
* </pre>
|
|
* The definition of the URI components has been extended to allow for
|
|
* internationalized domain names [2] and the more generic IRI structure [3].
|
|
*
|
|
* Note also that the RFC defines #-separated fragment identifiers as being
|
|
* "not part of the URI". Despite this, we bundle them as part of the URI, for
|
|
* convenience.

|
|
* AUTF8String attributes may contain unescaped UTF-8 characters.
|
|
* Consumers should be careful to escape the UTF-8 strings as necessary, but

* for sessionstore to work after an upgrade. If this IID is revved further,
|
|
* we will need to add additional checks there for all intermediate IIDs, until
|
|
* nsPrincipal is fixed to serialize its URIs as nsISupports (bug 662693).
