 ## Accessing the site
 After the template deployment is complete you can access requestbin site using the following urls: 
 
-* If you need https, you have to use `https://<name-specified-during-deployment>.azurewebsites.net`
+* If you need https, you have to use `https://<name-specified-during-deployment>.azurewebsites.net`. However, this will need some additional setup before it will work if you're using version `~4` of Azure Functions, as the proxies feature has been disabled. In order to re-enable it, on the Azure Portal, make sure the app setting `AzureWebJobsFeatureFlags` has the value `EnableProxies`. Although this re-enables the proxies feature, the `Proxies` menu item will remain grayed-out. See [Re-enable proxies in Functions v4.x](https://learn.microsoft.com/en-us/azure/azure-functions/legacy-proxies#re-enable-proxies-in-functions-v4x) for more information. For convenience, this app setting is included in the ARM template.
 * You can also access it using the ACI domain at `http://<name-specified-during-deployment>.<regionname-of-resourcegroup>.azurecontainer.io` where `<regionname-of-resourcegroup>` e.g. could be `westeurope` if you created the resource group in that region. Note this URL doesn't support https, as that is yet to come for ACI, which is why I included the azure function reverse proxy in the template, as you most likely need https.
