LogBook is a server-side application that lets you debug your web
application by showing the log messages related to your web request.
It stands in the tradition of
FirePHP and
ChromeLogger
but extracts the core functionality into a server-side log-dispatcher.
The reason is that for larger amounts of data, header fields are an
inappropriate way to send all the logs from a web-application to the client.
When you have a small application with few log events, it is quite easy
to send those data with your HTTP-header. But their are hard limits
that prevent you from sending as many log-data as a larger application
will provide. LogBook collects all those data in a server-side
application just to provide this information to the developer in an
JavaScript-based frontend-application.
