Abstract: A method, system and computer program product for managed object replication and delivery redirects, directly or indirectly, a client's request for an object that is not available at a best or optimal handling edge server of a network to a parent server that has the requested object. So, where the requested object is not available at the handling edge server, the client's request is redirected directly to the parent server that can provide the requested object to the client or indirectly via one or more parent servers to a parent server that can provide the requested object to the client. The method, system and computer program product further intelligently replicates the object to the edge server if the object is popular enough. Likewise, an object is removed from an edge server when it is no longer popular. All redirection and replication operations are preferably transparent to the end-user and do not degrade the quality of service.

Abstract: A filter includes filter media and a mesh panel secured to a face of the filter media. The mesh panel has a perimeter edge margin and intersecting web members that extend from the perimeter edge margin across the panel. A web member can have an outer web portion with a larger minimum width than an inner web portion. The web members can define an outer flow opening with a smaller cross-sectional opening than an inner flow opening defined by the web members. The flow openings can be diamond shaped. The web members can include one set of web portions that define an outer flow opening and another set that define an inner flow opening. The sum of the widths of the second set can be less than the sum of the widths of the first set.

Abstract: A content delivery method directs a request by a client for an object to a first server in a content delivery network (CDN), regardless of whether the first server has the requested object. If the first server has the requested object, then it is served to the client from the first server; otherwise, the first server redirects the client request to a second server in the CDN to handle the request. The second server may be a peer server of the first server. The first and second servers may be edge servers in the CDN.

Abstract: A client requests an object at a first server in a content delivery network (CDN), the request having been directed to said first server regardless of whether the first server has the requested object; When the first server does not have a copy of the requested object, it selectively replicating the requested object on the first server. The replicating is based at least in part on a measure of popularity of the requested object, wherein the requested object is not replicated to the first server when the measure of popularity of the requested object does not exceed a popularity threshold.

Abstract: An air filter including a filter media having a plurality of flat pleats defining a plurality of truncated pleat tips and sloping side surfaces along a front face and a rear face. The truncated pleat tips are oriented perpendicular to the direction of pleating and are configured with a planar tip portion. The reinforcement structure includes at least one generally planar first reinforcing strip oriented in the direction of the pleating and connected to the truncated pleat tips along the rear face. The reinforcing structure further includes at least one generally planar second reinforcing strip oriented in the direction of pleating and connected to the truncate pleat tips along the front face.
