The distribution network comprising a plurality of caching nodes and wherein the web content had been statically identified as an uncacheable content and originated on an origin-server and wherein the method establishes a time to live, TTL, period value to said uncacheable content based on users requests and responds to said users requests by sending to at least to one CDN user said uncacheable content within said TTL period value. Each one of said plurality of caching nodes in said distribution network including a content caching manager and a pseudo-dynamic content TTL predictor and performing the following steps: The system of the invention is arranged to implement the method of the invention.

Web caching method and system for content distribution network

A computer implemented method and network device for tracking OPT-OUT user preferences in a global communication network and computer programs thereof, The method comprising performing, by at least one a user, at least one operation request for a service of an online system (); tracking, by a network device (), said operation request and detecting if it is linked to a tracking mechanism, wherein: a) if it is not linked to a tracking mechanism, said network device (), bypasses the operation request to said online system () without performing any action; or if it is linked to a tracking mechanism, the network device (), identifies whether an OPT-OUT or an Opt-In status related to the user is included in the operation request and sends or not the operation request to a tracking server () depending on the result of said identification.

Computer-implemented method, a network device and computer program products for tracking OPT-OUT user preferences in a global communication network

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.
