11. Status page¶
The status page gives information about the AWS internal status. For example it returns the server socket ID, the number of simultaneous connection, the number of time a connection has been used…
To display the information AWS use a template file. The template file (default is aws_status.thtml) is an HTML file with some specific tags recognized by the parser. For more information about how the template parser works, please look for the template parser documentation distributed with AWS.
Here are the tag variables recognized by AWS status page:

A list of natural. One for each connection. This is the number of request the connection has answered. This counter is reset each time the connection is closed. In other word this is the number of request a keep-alive connection has processed.
