{{DISPLAYTITLE:al_version}}
'''al_version''' (AppletLoader version), saved on disc as <code>version</code>, is a number formerly used in versions as a caching identifier, to uniquely identify <samp>.jar</samp> files to be cached.

It is needed because the game used to be hosted on [[Minecraft:Minecraft.net]] as an applet.
The al_version value was used to tell the LWJGL AppletLoader when to clear its cache so LWJGL and [[Minecraft:client]]jars could be updated automatically.

== Usage ==
al_version is a number given as a parameter to the LWJGL AppletLoader in the HTML code of <code>[[Minecraft:minecraft.net]]/play.jsp</code>.<ref>[https://web.archive.org/web/20090525130611/http://minecraft.net/play.jsp Minecraft.net/play.jsp] (source) – Wayback Machine, May 25, 2009. "''<param name="al_version" value="5.17">''".</ref>
It is used to specify a unique version for each jar file to cache them for re-use. (To save on downloads, the site would used a cached version on disc if the game is marked as being the same as the last time it was downloaded.)
If the stored al_version matches the latest jar files, those jar files are re-used; otherwise the previously saved jars are removed from the cache and new ones are downloaded.

From Classic through most of Infdev, the al_version was a positive floating point number. Starting from [[Minecraft:Infdev 20100629]], al_version proper was no longer used, however a caching ID still remained, taking the form of the current timestamp of the version's release.

== Storage location ==
The al_version may be found in the HTML of the game's web applet, as <code><param name="al_version" value="[''al_version_id'']" /></code>

In Classic through Infdev, the al_version may be found on disc in the temporary directory as <code>version</code>. The path differs based on the URL of the web applet being used:
*<code>%temp%/Minecraft/</code>
*<code>%temp%/www.minecraft.net/Minecraft/</code>
*<code>%temp%/minecraft.net/Minecraft/</code>
*<code>%temp%/www.minecraft.net/Minecraft_creeper_test/</code>
*<code>%temp%/minecraft.net/Minecraft_creeper_test/</code>
*<code>%temp%/www.minecraft.net/Minecraft_sneakpeek/</code>
*<code>%temp%/minecraft.net/Minecraft_sneakpeek/</code>
*<code>%temp%/www.minecraft.net/Minecraft_infdev/</code>
*<code>%temp%/minecraft.net/Minecraft_infdev/</code>
*<code>%temp%/www.minecraft.net/Minecraft_game/</code>
*<code>%temp%/minecraft.net/Minecraft_game/</code>

Starting from Infdev 20100629, with the change from float al_version to a timestamped cache ID, it is now located on disc at <code>%appdata%/.minecraft/bin/</code> (used by www.minecraft.net/game/ and the offline launcher).
