A system and a method for replacing error messages with non-error messages. The system includes a network device for sending a query, a server device for receiving the query and a non-error message generator for generating and sending a non-error message to the network device. Alternately, the system may include a network device for sending the query and a server device, for receiving the query and for determining whether the query is resolvable. If the query is non-resolvable, the server device forms the non-error message and sends it to the network device. The method may include the steps of providing a network device, providing a server, sending the query to the server, receiving the query and generating the error message if the query is not resolvable by the server, intercepting the error message and altering the error message to form the non-error message sending the non-error message to said network device. Alternately, the method may include the steps of providing a network device, providing a server, sending a query from the network device to the server, receiving the query at the server and generating the error message if the query is not resolvable by the server, and intercepting the error message received at the network device to send a non-error message in place of the error message. |

DETAILED DESCRIPTION The present invention is of a system and a method for replacing error messages, received from a server as a result of requests which are not resolvable, with non-error messages.
The non-error messages can include substantially any type of content or information, such as advertisements, promotional or other information for products, persons or ideas, publications, educational materials, public service announcements or substantially any other types of information, or a link to one or more additional resources through a resource address.
For example, the method of the present invention could be used to replace errors generated by an address resolution server, such as a DNS (domain name service) server, by non-error messages.
The non-error messages may redirect the software application requesting the address resolution to a particular Web page, for example.
This particular Web page is optionally specific to the particular resource name, to the type of software program requesting the resource address resolution, and/or to the identity or other properties of the requesting user.
Preferably, the non-error message is generated by a hardware device and is then sent by this hardware device to the software program requesting the address resolution, instead of the error message.
However, the error message may also be replaced by software components, including but not limited to, drivers and software programs, running either on the server computer, the client computer or another computer system between the server computer and the client computer.
The error message is optionally replaced explicitly, in that the error message is actually generated before being replaced in a two-stage process; or implicitly, in that the non-error message is generated rather than the error message, in a single stage process.
Other examples include error messages generated by other servers such as HTTP (Hypertext Transfer Protocol) servers, E-mail servers, FTP (File Transfer Protocol) servers, or Telnet servers, and error messages generated by a firewall in place of a server, when a particular request is not permitted
