Abstract: A distributed health-check method for web caching in a telecommunication network, wherein a plurality of web caching nodes are coordinated to monitor a set of origin servers where web content is generated. The method includes associating to each user of the telecommunication network requesting the web content buckets as logical containers for holding the web content requested; generating a list of users of the telecommunication network requesting the web content; and performing the plurality of web caching nodes a number of health-checks to the set of origin servers to download the requested web content. A filtering of the set of origin servers is performed for grouping in different areas of interest and the number of health-checks are performed by a limited number of caching nodes receiving the web content requests. The limited number of caching nodes selected belonging to a specific area of interest of the set of origin servers monitoring them.
