Abstract
Methods and systems for indexing content in a cache data structure within a content cache are disclosed. The methods and systems identify at least one characterization data associated with a received content request and input the at least one characterization data into a hash function to generate an index that is used for identifying an entry associated with the requested content in the cache data structure. The at least one characterization data may include a portion of content associated with the received content request, a portion of a Uniform Resource Locator (URL) associated with the received content request, an IP address associated with the received content request, the length of the content associated with the received content request, and one or more parameters parsed from the URL associated with the received content request.
