PLUGINURL

PLUGINURL is used by Netscape Communicator's JAR Installation Manager. PLUGINURL points to a "JAR archive" which is a resource used to automatically install the plugin (so they say, I've had all kinds of problems with Netscape's "automatic" stuff). JAR archives are a special type of compressed files originally used for Java; see <APPLET ARCHIVE="...">.
