# Configure Request and Response Proxy Buffers

Azure Application Gateway Standard v2 SKU supports buffering Requests (from clients) or Responses (from the backend servers). Based on the processing capabilities of the clients that interact with your Application Gateway, you can use these buffers to configure the speed of packet delivery.

## Response Buffer
1818

19-
Application Gateway's Response buffer can collect all or parts of the response packets sent by the backend server, before delivering them to the clients. By default, the Response buffering is enabled on Application Gateway which is useful to accommodate slow clients. This setting allows you to conserve the backend TCP connections as they can be closed once Application Gateway receives complete response and work according to the client's processing speed. This way, your Application Gateway will continue to deliver the response as per client’s pace.

## Request Buffer

In a similar way, Application Gateway's Request buffer can temporarily store the entire or parts of the request body, and then forward a larger upload request at once to the backend server. By default, Request buffering setting is enabled on Application Gateway and is useful to offload the processing function of re-assembling the smaller packets of data on the backend server.

## Limitations

- API version 2020-01-01 or later should be used to configure buffers.
88-
- Currently, these changes are not supported through Portal and PowerShell.
89-
- Request buffering cannot be disabled if you are running the WAF SKU of Application Gateway. The WAF requires the full request to buffer as part of processing, therefore, even if you disable request buffering within Application Gateway the WAF will still buffer the request. Response buffering is not impacted by the WAF.

This will be configurable and a more clear exception will be implemented as part of [this host work item](https://github.com/Azure/azure-functions-host/issues/10482).

Also, with the Azure Storage provider, consider reducing the [queue polling interval](./durable/durable-functions-azure-storage-provider.md#queue-polling) to 10 seconds or less.

The subnet delegation required by Flex Consumption apps is `Microsoft.App/environments`.
142142
+ **Triggers**: All triggers are fully supported except for Kafka and Azure SQL triggers. The Blob storage trigger only supports the [Event Grid source](./functions-event-grid-blob-trigger.md). Non-C# function apps must use version `[4.0.0, 5.0.0)` of the [extension bundle](./functions-bindings-register.md#extension-bundles), or a later version.

+ There is a temporary limitation where App Service quota limits for creating new apps are also being applied to Flex Consumption apps. If you see the following error "This region has quota of 0 instances for your subscription. Try selecting different region or SKU." please raise a support ticket so that your app creation can be unblocked.
