First Claim
Patent Images
1. In a computer network including a plurality of server systems connected through a network to a plurality of client systems, at least one of the server systems having access to a listing, a method of at least one of the client systems accessing a row range of the listing without having to download the entire listing and without having to specify the exact location of the row range within the listing, the method comprising the following:
- a step for a client system generating a HyperText Transport Protocol (HTTP) request for the row range of the listing, the request including an identification of a reference row in the listing by using a property of one or more fields within the reference row rather than by using the reference row'"'"'s precise sequential position in the listing, the request identifying the row range of the listing relative to the reference row;
a specific act of the client system transmitting a single HTTP request that includes an identification of the reference row along with an identification of the row range using the reference row over the network so as to be received by the server system that has access to the listing; and
a specific act of the client system receiving an HTTP response over the network from the server that has access to the listing, wherein the response includes at least the row range of the listing.

Abstract
A method is described in which a client computer generates an HTTP request and transmits the request to a server computer that has access to a listing such as an e-mail listing, a directory listing, or a table. The HTTP request includes an identification of a number of row ranges within the listing. The server computer responds by transmitting an HTTP response that includes the number of row ranges back to the client computer. Since the entire listing need not be downloaded, and since a separate HTTP request is not required for each row range, time is conserved. In another method, the request includes an identification of a reference row other than by the row'"'"'s exact sequential position in the listing. The row range is identified with respect to the reference row. Since row numbers for each given row can often change in frequently edited listings, the present invention more accurately downloads the desired rows.
