Al version

al_version (AppletLoader version) is a number used in versions prior to Java Edition Alpha to uniquely identify a client version of the game.
== Usage ==
al_version is a positive floating-point number given as a parameter to the LWJGL AppletLoader in the HTML code of minecraft.net/play.jsp.Minecraft.net/play.jsp (source) – Wayback Machine, May 25, 2009. "<param name="al_version" value="5.17">".
It is used to specify a unique version for each jar file to cache them for re-use.
If the stored al_version matches the latest jar file, that jar file is re-used; otherwise a new jar is downloaded.
