110 | ||
111 | <glossdef> | |
112 | <para>A set of modifications to the operating system on a client machine which enables users on the machine to access files | |
113 | stored in AFS. The Cache Manager requests files from the File Server and stores (<emphasis>caches</emphasis>) a copy of each | |
114 | file on the client machine's local disk. Application programs then use the cached copy, which eliminates repeated network | |
115 | requests to file server machines.</para> | |

131 | <para>A promise from the File Server to contact the Cache Manager if the centrally stored copy of the file changes while the | |
132 | Cache Manager has a cached copy. If the file is altered, the File Server <emphasis>breaks</emphasis> the callback. The next | |
133 | time an application program asks for data from the file, the Cache Manager notices the broken callback and retrieves an | |
134 | updated copy of the file from the File Server. Callbacks ensure the user is working with the most recent copy of a | |
135 | file.</para> | |
