Forms Standalone Launcher and HTTP for -jar Option

I'm starting a Forms application using the java.exe -jar option so we can point at the forms standalone launcher jar [FSAL]. What location schemes does this support? The following work

• java.exe -jat c:\jar.jar
• java.exe -jar \\server\share\jar.jar

The following does not work:

• java.exe -jar https://server/jar.jar
• java.exe -jar http://server/jar.jar

Hosting the JAR files on a web server would be highly desirable for our use case.
