Abstract:
1. A computer-implemented method for indicating availability of a network resource in a client-server environment, the method comprising: providing at least one computing device for performing the following: querying the network resource, using a query component, to determine network resource availability and response time, and setting a status indicator with respect to the network resource availability, using a status component; in the case that the status indicator indicates that the network resource is available, determining whether a query of the network resource to determine network resource availability and response time is occurring; in the case that a query is occurring, setting the status indicator to indicate the network resource is available only if a time of the query is less than a specified response time, wherein the specified response time is calculated based on a range of response times determined by an average query completion time and a standard deviation of an average query completion time, a portion of the standard deviation of the average query completion time indicating an unacceptably long query time, the average query completion time determined using the response time only in the case that the network resource is available; and dynamically updating the average query completion time and the specified response time, using the query component, by repeatedly querying the network resource.
