A content delivery network service provider determines a class associated with a set of client computing devices and monitors resources requests for the determined class. The content delivery network service provider then identifies at least one cache component for providing content to client computing devices as a function of the determined class. In other embodiments, instead of cache components, the content delivery network service provider identifies a second set of client computing devices as a function of the determined class for providing the content information. ## Claims ### Claim 1 A method comprising: obtaining a request for content from a first client computing device at a content delivery network (CDN) service provider; determining a class of client computing devices associated with the first client computing device based on a first criterion, wherein the first criterion is associated with a subset of the client computing devices serviced by a first cache component of the CDN service provider and wherein the first criterion comprises a first temporal domain associated with a location of the first client computing device; associating the class of client computing devices with the requested content; selecting a second cache component from a plurality of cache components of the CDN service provider, wherein the second cache component is different from the first cache component, wherein the second cache component is selected based on servicing a subset of client computing devices that do not comprise the first criterion, and wherein the subset of client computing devices serviced by the second cache component comprises a second temporal domain; and selectively preloading the requested content at the second cache component based at least in part on a common second criterion comprised by the class of client computing devices and the subset of client computing devices serviced by the second cache component. ### Claim 2 (depends on 1) The method of claim 1, wherein determining the class comprises observing behavior associated with resource requests from a plurality of client computing devices over time and determining the class of client computing devices based on the observed behavior. ### Claim 3 (depends on 1) The method of claim 1, wherein the common second criterion is a time criterion and wherein preloading the requested content is based at least in part on the time criterion corresponding to a time range when the content was requested. ### Claim 4 (depends on 1) The method of claim 1, wherein the common second criterion is a time criterion. ### Claim 5 (depends on 4) The method of claim 4, wherein the time criterion comprises a time range within which the content was requested. ### Claim 6 A system comprising: a first network point of presence associated with a content delivery network (CDN) service provider, wherein the first network point of presence comprises at least one computing device that: obtains a request for content from a first client computing device at the CDN service provider; determines a class of client computing devices associated with the first client computing device based on a first criterion, wherein the first criterion is associated with a subset of the client computing devices serviced by a first cache component of the CDN service provider and wherein the first criterion comprises a first temporal domain associated with a location of the first client computing device; associates the class of client computing devices with the requested content; selects a second cache component from a plurality of cache components of the CDN service provider, wherein the second cache component is different from the first cache component, wherein the second cache component is selected based on servicing a subset of client computing devices that do not comprise the first criterion, and wherein the subset of client computing devices serviced by the second cache component comprises a second temporal domain; and selectively preloads the requested content at the second cache component based at least in part on a common second criterion comprised by the class of client computing devices and the subset of client computing devices serviced by the second cache component. ### Claim 7 (depends on 6) The system of claim 6, wherein determining the class comprises observing behavior associated with resource requests from a plurality of client computing devices over time and determining the class of client computing devices based on the observed behavior. ### Claim 8 (depends on 6) The system of claim 6, wherein the common second criterion is a time criterion and wherein preloading the requested content is based at least in part on the time criterion corresponding to a time range when the content was requested. ### Claim 9 (depends on 6) The system of claim 6, wherein the common second criterion is a time criterion. ### Claim 10 (depends on 9) The system of claim 9, wherein the time criterion comprises a time range within which the content was requested.
