title: Making two player chess app with Django-- need player's board to update when opponent makes a move
body: <p>So each player has their own webpage with a Javascript chessboard GUI interface, which they can click to drag pieces. When one player makes a move, I need the other player's chessboard to update with that move. I see how when one player makes a move, I can post the move to the server so that it's available for the other player to request it, but the problem is signaling the other player when a move is made, so they know when to request the new move from the server and use it to update the javascript on their page. What's a good technique to do this?</p>
