/*

The nsICoolURL class is an interface to the URL behaviour.
|
|
This follows the URL spec at-
|
|
|
|
http://www.w3.org/Addressing/URL/url-spec.txt
|
|
|
|
For the purpose of this class, here is the most elaborate form of a URL
|
|
and its corresponding parts-
|
|
|
|
ftp://username:password@hostname:portnumber/pathname
|
|
\ / \ / \ / \ /\ /
|
|
- --------------- ------ -------- -------
|
|
| | | | |
|
|
| | | | Path
|
|
| | | Port
|
|
| | Host
|
|
| PreHost
|
|
Scheme
|
|
|
|
The URL class extends the URI behaviour by providing a mechanism
|
|
for consumers to retreive (and on protocol specific levels put)
|
|
documents defined by the URI.
|
|
|
|
Functions missing from this file are the stream listener portions
|
|
for asynch operations. TODO.
|
|
|
|
Please send me a mail before you add anything to this file.
