 ### Consistent routing through virtual networks
 
-Multiple function apps hosted in the same plan can also use the same storage account for the Azure Files content share, defined by `WEBSITE_CONTENTAZUREFILECONNECTIONSTRING`. When you secure this storage account by using a virtual network, all of these apps should use the same value for `vnetContentShareEnabled` (formerly `WEBSITE_CONTENTOVERVNET`) to ensure that traffic routes consistently through the intended virtual network. A mismatch in this setting between apps that use the same Azure Files storage account might result in traffic routing through public networks. In this configuration, storage account network rules block access.
