due to the resources available to the user's Web clients." (Col. 4,
ll. 10-16.)
5. To reduce latency, Acharya teaches that a memory cache may be
provided by an Internet Service Provider on a proxy computer. (Col.
3, ll. 6-7.) If a copy of a requested file is in the cache, it is forwarded
to the user's client computer provided that the file is not stale. (Col. 3,
ll. 19-23.) Methods for determining whether a cached file is stale are
well known. (Col. 3, ll. 23-24.)
6. In the method taught by Acharya, a user may request and receive files
in various formats and resolutions. (Col. 4, ll. 47-49; col. 8, ll. 36-42.)
"A user first determines information content the user wishes to
receive." (Col. 4, ll. 53-54.) The user requests transmission of the
file by selecting a hyperlink on a Web page being viewed. (Col. 4,
ll. 50-53; col. 9, ll. 21-22.)
7. Acharya teaches that "[w]hen a user first requests a Web page that he
wishes to receive, . . . the server specified in the URL responds by
transmitting a skeleton of the Web page to the client, the skeleton
containing links or pointers to images and/or other files embedded
within the Web page." (Col. 8, ll. 58-64.) "The Web browser then
automatically requests these embedded files from the server to load
the Web page." (Col. 8, ll. 64-66.)
