 ## How the local cache changes the behavior of App Service
 * _D:\home_ points to the local cache, which is created on the VM instance when the app starts up. _D:\local_ continues to point to the temporary VM-specific storage.
-* The local cache contains a one-time copy of the _/site_ and _/siteextensions_ folders of the shared content store, at _D:\home\site_ and _D:\home\siteextensions_, respectively. The files are copied to the local cache when the app starts up. The size of the two folders for each app is limited to 300 MB by default, but you can increase it up to 2 GB.
+* The local cache contains a one-time copy of the _/site_ and _/siteextensions_ folders of the shared content store, at _D:\home\site_ and _D:\home\siteextensions_, respectively. The files are copied to the local cache when the app starts up. The size of the two folders for each app is limited to 300 MB by default, but you can increase it up to 2 GB. Should the files copied exceed the size of the local cache, the App Service will silently ignore local cache and read from the remote file share.
 * The local cache is read-write. However, any modification is discarded when the app moves virtual machines or gets restarted. Do not use the local cache for apps that store mission-critical data in the content store.
 * _D:\home\LogFiles_ and _D:\home\Data_ contain log files and app data. The two subfolders are stored locally on the VM instance, and are copied to the shared content store periodically. Apps can persist log files and data by writing them to these folders. However, the copy to the shared content store is best-effort, so it is possible for log files and data to be lost due to a sudden crash of a VM instance.
 * [Log streaming](troubleshoot-diagnostic-logs.md#stream-logs) is affected by the best-effort copy. You could observe up to a one-minute delay in the streamed logs.

 ## Change the size setting in Local Cache
-By default, the local cache size is **1 GB**. This includes the /site and /siteextensions folders that are copied from the content store, as well as any locally created logs and data folders. To increase this limit, use the app setting `WEBSITE_LOCAL_CACHE_SIZEINMB`. You can increase the size up to **2 GB** (2000 MB) per app.

 ## Best practices for using App Service Local Cache
 We recommend that you use Local Cache in conjunction with the [Staging Environments](../app-service/deploy-staging-slots.md) feature.
