Appendix F Traffic Server Error Messages
HTML messages sent to clients
Traffic Server returns detailed error messages to browser clients when there are problems with the HTTP
transactions requested by the browser. These Traffic Server response messages correspond to standard HTTP
response codes, but provide more information. A list of the more frequently encountered HTTP response codes
is provided on page 232. You can customize Traffic Server’s response messages.
The following table lists Traffic Server’s hard-coded HTTP messages, their corresponding HTTP response
codes, and their corresponding customizable files.
