[mapguide-users] Re: Use tile cache in different maps

[Jackie Ng]

Unlike the AJAX viewer, the development platform in Fusion is not
PHP/.net/Java. It is javascript.

The only time PHP/.net/Java is involved is when you need to cover
functionality that is not exposed by the HTTP mapagent or you have a need to
integrate with 3rd party web applications/services. And in this respect PHP
was chosen for the Fusion backend because:

 1. It works on both Windows and Linux
 2. No JRE or netfx redistributable requirement.
 3. Zero-configuration. No need to setup/configure virtual directories
and/or servlet containers.
 4. Regardless of your installation options, PHP is always installed (as it
is required by the Site Administrator)

Yes we could have a .net or java Fusion backend, but that is a clear
violation of DRY and is pretty pointless for a *client-side* framework like
Fusion. The AJAX viewer *had* to exist in 3 different languages due to its
pre-web2.0, frame-based, server-centric design. Fusion does not, but that
doesn't mean your server development platform is restricted to PHP.

There is nothing stopping you from having .net/java Invoke URL commands in
Fusion, and there's nothing stopping you from creating new widgets with
.net/java backends. It's just that the server-side infrastructure in Fusion
is done in PHP, I presume, is because it is the language with the broadest
platform reach for the reasons already stated above.
