Abstract: A shank of a milling cutter can be somewhat elastic. As a result, during plunging down into a workpiece the milling cutter will not plunge in a true axially downward direction and will form a slanted wall in the workpiece. A milling cutting insert is provided which is capable of “straightening out” the slanted wall. The cutting insert has a rear cutting edge which removes material when the milling cutter is moved axially upwardly.

Abstract: A process for creating server-driven dynamic web content without the use of browser add-ins or plug-in programs. Rather than relying on a plug-in on the browser side, the server uses an independent and persistent HTTP connection to stream commands to the browser that result in dynamic updates of the displayed web page. When a browser requests a page that will be dynamically updated from the server side, the server makes an HTTP reply that results in the browser making at least two HTTP requests. The first request results in the server providing a display page. The second request establishes an independent HTTP connection that serves as a control stream for the server to send commands to the browser. The commands are implemented through the document object model of the browser and result in the dynamic updating of the display page.
