The communication link a remote WAP terminal (2) and a server (1). The terminal uses applications (3,4) within two families, offering different degrees of reliability. Each request includes a marking identifying which family of applications the request comes from, for the information of the server in handling the request. The communication system provides a link between two units (1,2). The first unit (2) comprises applications (3,4) which belong to first and second families of applications respectively. The second family offers a degree of reliability which is, a priori, weaker than that of the second family. Each request issued by an application within the second family (4), transmitted over the network (R) to a the remote server unit (1), is constrained both to include marking identifying it as part of the second family of applications, and not to include marking relating to the first family of applications. This marking relating to the first family is only included with requests which are transmitted on the network having been originated by applications from within the first family (3). The marking relating to the second family includes an indication of the nature and/or the origin of the second family application. The information may also be signed, to include data relating to the certification of the signature. |
