The present invention provides a cloud service packet redirection method and system, and a cloud gateway, the method performed by the cloud gateway includes, if the cloud gateway determines that a DNS packet that is forwarded by a router in a redirection manner is a cloud service-related DNS packet, a record is maintained in a cloud IP table of the cloud gateway according to the DNS packet. In one embodiment, the composition optionally contains at least one adjunct selected from the group consisting of solvents, surfactants, cosurfactants, chelating agents, buffers, thickeners, dyes, colorants, biocides, fragrances, defoamers and mixtures thereof. The collector 13a contains aluminum and at least one element other than aluminum. The material is positioned at a location lying within at least one of the electric and magnetic field responses so-generated. The driving mechanism is mounted on the frame unit for driving the connecting rod to rotate to thereby convert the driven mechanism between the unfolded and folded states.
