Use the cache.xml file to set up general cache facilities and behavior and to create and initialize cached data regions. These sections document cache.xml requirements; provide hierarchical diagrams of `<cache>` and `<client-cache>         `elements; and describe the function of each element.

**Note:**
You can configure most elements of the cache.xml file and apply it to your entire cluster by using the [gfsh](../../tools_modules/gfsh/chapter_overview.html) and [cluster configuration service](../../configuring/cluster_config/gfsh_persist.html). See [gfsh Limitations](../../configuring/cluster_config/gfsh_persist.html#concept_r22_hyw_bl__section_bn3_23p_y4) for a list of items you cannot configure in gfsh and must still configure in cache.xml.

-   **[cache.xml Quick Reference](../../reference/topics/elements_ref.html)**

    This section documents cache.xml file requirements and variables. It also points you to specific element sections for server, client, and WAN configuration.

-   **[&lt;cache&gt; Element Hierarchy](../../reference/topics/cache-elements-list.html)**

    This section shows the hierarchy of `<cache>` element sub-elements that you use to configure <%=vars.product_name%> caches and servers.

-   **[&lt;cache&gt; Element Reference](../../reference/topics/cache_xml.html)**

    This section documents the `cache.xml` sub-elements used for <%=vars.product_name%> server configuration. All elements are sub-elements of the `<cache>` element.

-   **[&lt;client-cache&gt; Element Hierarchy](../../reference/topics/client-cache-elements-list.html)**

    This section shows the hierarchy of `<client-cache>` element sub-elements that you use to configure <%=vars.product_name%> caches and clients.

-   **[&lt;client-cache&gt; Element Reference](../../reference/topics/client-cache.html)**

    This section documents all `cache.xml` elements that you use to configure <%=vars.product_name%> clients. All elements are sub-elements of the `<client-cache>` element.
