Apparatus and a process for the retrieval of data in the case of a faulty request on a server in the internet
First Claim
1. An apparatus for a retrieval of alternative data in the case of a faulty request of a client to a server in a packet-based network, a. with a network interface which enables a data stream between the client and the server to be analysed, b. with a processing unit which checks the data stream following the request of the client, wherein a data pattern that indicates an error message from the server is blocked and replaced by alternative data, wherein said alternative data depends on the content and type of request, wherein said alternative data will be sent to the client using the network interface.

Abstract
This invention relates to an apparatus and a process for the retrieval of alternative data in the case of a faulty request by a client on a server in a network (such as the internet). Included is a network interface (12) which enables the stream of data between a client (11) and server (20) to be analysed. The network interface (12) has a processing unit (18) which checks the traffic of data in the case of a faulty request by the client. The error messages from the server will be blocked and replaced by alternative data, based on the nature of the search. This alternative data (19) will then be sent to the client (11) by the network interface (12).

2. An apparatus for a retrieval of alternative data, in particular a proxy, in the case of a faulty DNS or URL request of a client to a server in a IP network,
a. with a network interface which enables a IP data stream between the client and the server to be analysed, b. with a processing unit which checks the data stream following the DNS or URL request of the client, wherein a data pattern that indicates an error message from the server is blocked and replaced by alternative data, wherein said alternative data is an IP address or a HTML page depending on the content and type of request, wherein said alternative data will be sent to the client using the network interface.

10. A process, for the retrieval of alternative data in the case of a faulty request of a client to a server in a packet-based network,
a. with a step in which a stream of data between said client and said server is analysed, b. with a further step in which an error message from said server caused by a faulty request of said client is blocked, c. with a further step in which alternative data is produced, depending on the nature and/or content of said request, d. with a further step in which said alternative data, not the server'"'"'s original response, will be sent to the client.

11. A process, in particular used by a proxy, for the retrieval of alternative data in the case of a faulty DNS request or URL request of a client to a server in a IP network,
a. with a step in which data packets between said client and said server are analysed, b. with a further step in which an error message from said server in the case of a faulty request by the client is blocked, c. with a further step in which alternative data in form of an IP address or a HTML page is produced, wherein the alternative data depends on the nature and/or content of said request, d. with a further step in which said alternative data, not the server'"'"'s original response, will be sent to the client.
