Figure under ?Support for older browsers?

The figure under ?Support for older browsers? is identical to the one appearing at the top of page 40 and does not correspond to the text the figure is supposed to support:

?A problem that might arise when we open the connection using the start() method is that the user?s browser might be too old and not have the JSON parser built in?for example, as it happens with Internet Explorer 7. In this case, execution will stop, indicating the problem and even its solution:?

Startup.cs

Using a Kindle app so the page number may not apply. At the end of Chapter 4 in the source for tracking.js is the following line

var connection = $.connection("/tracker");

This will work in IIS Express but not in the full IIS 8.5 on Server 2012 R2. Remove the leading "/" i.e. $.connection("tracker"); and it will work on both.

The same for the Drawing Board sample at the end of Chapter 5, Hubs Figure 5-18 drawingboard.html

Remove the leading "/" from <script src="/signalr/js"></script>

i.e. <script src="signalr/js"></script>

to run in both IIS Express and full IIS
