A method of transmitting an electronic data set between a provider server (2) and a user computer (1), the electronic data set in the provider server (2) being included in an electronic directory and being stored in said directory under a designation, and a communication address in a network, which comprises the provider server (2) and a server means (3), being assigned to the electronic directory so that the electronic data set is electronically identifiable in the network by means of a data set address which comprises the communication address and the designation, said method comprising the following steps:

  • (a) electronically recording a user request generated by a user by means of a browser in the user computer (1) for retrieval of the electronic data set from the electronic directory in the provider server (2) by way of the server means (3);

    (b) automatically requesting and recording user data for authentication of the user by way of the server means (3) and the user computer (1);

    (c) electronically processing the user data recorded and the information about the electronically recorded user request in the server means (3) for authorizing the user such that it is checked automatically by means of release information stored in the server means (3) whether any information about a current release for the electronic directory is electronically stored in the server means (3) for the user authenticated by the user data recorded;

    (d) transmitting the electronic data set of the electronic directory from the provider server (2) to the server means (3) and from the server means (3) to the user computer (1) if it is determined by the automatic checking according to method step (b) that the authenticated user is authorized;

    (e) syntactically analyzing the electronic data set by way of the server means (3) for electronically recording hyperlink elements which are included in the electronic data set and each comprise a different data set address pointing to an associated data set in the network, especially in the provider server (2);

    (f) electronically rewriting the data set address of one of said hyperlink elements prior to transmission of a part of the electronic data set which includes the hyperlink element from the server means (3) to the user computer (1) according to method step (d) if it is determined in the electronic checking of the one hyperlink element that the data set address of the one hyperlink element lies within the electronic directory, the electronic rewriting being carried out such that a rewritten data set address of the one hyperlink element is generated which address points to the server means (3); and

    (g) storing an electronic allocation between the data set address of the one hyperlink element and the rewritten data set address of the one hyperlink element by way of the server means (3) so that, upon a user request for retrieval of the data set belonging to the data set address of the one hyperlink element, transmission of the associated data set with involvement of the server means (3) is guaranteed.
