HTML messages sent to clients

Websense Content Gateway returns detailed error messages to browser clients when there are problems with the HTTP transactions requested by the browser. These response messages correspond to standard HTTP response codes, but provide more information. A list of the more frequently encountered HTTP response codes is provided in Standard HTTP response messages. You can customize the response messages.

The following table lists the Content Gateway hard-coded HTTP messages, their corresponding HTTP response codes, and their corresponding customizable files.

Connection Timed Out	504	Server has not sent any data for too long a time.	timeout#inactivity
Content Length Required	400	Could not process this request because no Content-Length was specified.	request#no_content_length
Cycle Detected	400	Your request is prohibited because it would cause an HTTP proxy cycle.	request#cycle_detected

Alternatively, end users can upgrade to a browser that supports the HTTP Host header field.	interception#no_host
