Three ways immediately come to mind (designed to be accessed by a
program via something like CFHTTP):
1) A data-drop site (page)... one that returns a WDDX packet when the page as
accessed.
For example A Manufacturer creates a page which returns a WDDX packet
containing a database query or a recordset of changes to its products
database.
Distributers can access the page with a program which uses the
WDDX packet to
update its own copy of the database.
2) A intelligent data-exchange site (page)... one that allows the visitor to
make requests and receive WDDX packets containing the results of the
requests.
For example, a publisher allows other sites to republish articles.
The republisher is provided with a program which can browse and
mark articles
to be retrieved from the publisher,
When through, the republisher sends a request to retrieve the articles. The
intelligent data-exchange page builds a custom WDDX packet containing only
the requested articles (including content and markup).
The republisher uses this WDDX packet to populate his database and/or web
pages
3) An interactive site (page)... where WDDX packets are the medium of exchange,
primarily because they easily handle complex data structures and special
character content which would be prohibitive to handle by other means.
The interactive database stub I described earlier in this thread, is an
example of this... essentially a program on one site accessing a
database on another.
Any, or all of these WDDX-Friendly sites (pages) can require whatever
security that the provider deems necessary - including, but not
limited to:
controlled access (cookie, login, IP address, etc.)
time-limited window of availability
unpublished site (page) address
data encryption
SSL transmission
These are exactly the types of applications that WDDX was designed to
address. An additional advantage, is that WDDX allows all of these
interacting programs to be written in different languages (Perl, ASP,
Java, JavaScript, C++, CF).
WDDX is kind of the ultimate medium for data exchange:
a XML packet contains A WXXX packet...
... this WDDX packet can contain arrays, structures, recordsets...
and, yes, it can contain an XML packets which can contain....
