`steps of:
`
`32b. providing a memory storing a cache of digital
`content, and a plurality of policies; and
`

`contents, the policy index including entries that relate
`cached content and policies by indicating pieces of
`cached content known to be allowable relative to a given
`policy, for each of a plurality of policies, comprising:
`
`32d. determining, based on a profile of a piece of digital
`content, whether the piece of digital content is
`allowable for a given user policy; and
`
`32e. storing an indication of the results of said
`determining whether the piece of digital content is
`allowable within the policy index, comprising:
`
`32f. if the piece of digital content is not already resident
`in the cache, then adding the piece of digital content
`into the cache; and adding an entry in the policy index
`indicating the allowability or the non‐allowability of the
`piece of digital content relative to the given user policy,
`based on the result of said determining;
`
`32g. else if the piece of digital content is already resident
`in the cache, then modifying an already existing entry in

`Caching at Secure Gateways
`
`Claim 17
`
`17a. A computer‐readable storage medium
`storing program code for causing a computer
`to perform the steps of:
`
`17b. retrieving a requested file from the
`Internet;
`
`17c. scanning the retrieved file to determine
`computer commands that the file is
`programmed to perform;
`
`17d. deriving a security profile for the
`retrieved file, the security profile including a
`list of at least one computer command that
`the retrieved file is programmed to perform;
`
`17e. storing the retrieved file within a file
`cache for future access, and indexing the
`retrieved file in the file cache with a file ID;
`and
`
`17f. storing the security profile for the
`retrieved file within a security profile cache
`for future access, and indexing the security
`profile in the security profile cache with the
`file ID of the retrieved file, so that when the
`same file is subsequently requested from the
`Internet, its security profile is readily
`accessible from the security profile cache
`without the need to perform the scanning.
`
`17a. A computer-readable storage medium storing program code for causing a computer to
`perform the steps of:
`
`The computer-readable storage medium described herein include RAM, ROM, floppy disks, CD,
`portable memory storage devices, and similar media for storing the Qualys software for the Accused
`Products.
