-  By default, HTTP requests are logged upon termination so that the total
-  transfer time and the number of bytes appear in the logs. When large objects
-  are being transferred, it may take a while before the request appears in the
-  logs. Using "option logasap", the request gets logged as soon as the server
-  sends the complete headers. The only missing information in the logs will be
-  the total number of bytes which will indicate everything except the amount
-  of data transferred, and the total time which will not take the transfer
-  time into account. In such a situation, it's a good practice to capture the
-  "Content-Length" response header so that the logs at least indicate how many
-  bytes are expected to be transferred.
+  By default, logs are emitted when all the log format variables and sample
+  fetches used in the definition of the log-format string return a value, or
+  when the session is terminated. This allows the built in log-format strings
+  to account for the transfer time, or the number of bytes in log messages.
+
+  When handling long lived connections such as large file transfers or RDP,
+  it may take a while for the request or connection to appear in the logs.
+  Using "option logasap", the log message is created as soon as the server
+  connection is established in mode tcp, or as soon as the server sends the
+  complete headers in mode http. Missing information in the logs will be the
+  total number of bytes which will only indicate the amount of data transfered
+  before the message was created and the total time which will not take the
+  remainder of the connection life or transfer time into account. For the case
+  of HTTP, it is good practice to capture the Content-Length response header
+  so that the logs at least indicate how many bytes are expected to be
+  transfered.
