Invalid Request - EdgeWave iPrism Web Security Administration Manual

iPrism
If multiple (or all) web servers are showing the same symptoms, iPrism's DNS service is unable to
operate because its DNS master (if one is used) may be unreachable, or because it can not perform
direct DNS requests. This would occur if a firewall were blocking ports UDP/53 and/or TCP/53.
Wait awhile and check the URL again; if the error occurs across multiple web servers, check iPrism's
DNS configuration and status.

Invalid Request

The "Invalid Request" error occurs when the syntax of the HTTP request submitted to iPrism is not
valid and does not follow the HTTP protocol. A possible reason is that the request did not include the
HTTP/1.x information on the HTTP request line. This error is infrequent in web browsers and more
often occurs with other HTTP applications.
Check the request syntax as displayed by iPrism and fix the client software.
Invalid URL
The "Invalid URL" error occurs if iPrism detects that the request does not respect the HTTP RFC. In
short, the syntax of the URL is incorrect. The usual reason this occurs has to do with invalid
characters in the URL, and may happen if the web page contains such an invalid URL as a link.
Check the request's syntax. If the URL is a link on a web page, you can also inform the remote
website's administrator.
iPrism is in the Process of Reconfiguring Itself
iPrism displays this message while a reconfiguration is in progress.
If the administrator made a change to the configuration, iPrism reloads its configuration. This is a
short-lived condition and the message should go away within 10 seconds.
Retry after a few seconds. If the error message does not go away contact Technical Support at:

Zero Sized Reply
The "Zero Sized Reply" error occurs when no data is returned in the HTTP connection. This may
happen under the following conditions:
