I am trying to create a rule in Azure Front Door to match the first folder in the request path and then use that to set a request header to the back-end origin group.
https://myfd.azurefd.net/**config**/some1/some2/some3/test.html
https://myfd.azurefd.net/**identity**/some1/some2/some3/
I was able to do this in Application Gateway and get it to work as follows:
App Gateway Config
However, I cannot get this to work in FD as per the following config:
Azure Front Door Config
Azure Front Door is offering 3 tiers of services; the feature and optimization "Regular expression in the rules engine" is not available in the Classic tier. It was the root of the problem here. Consider the Standard or Premium tiers. Please see the screenshot below.
Step1:
Front Door created with Premium tier
Step2:
Created a rule engine with Regular expression
hope this helps!

I have to migrate an azure Front door classic configuration to Premium sku profile, however there are some differents between this two versions.
This is my rule engine configuration on Classic:
And this is my rule engine configuration on Premium:
How should I complete this form to have the same configuration on my Premium Profile?
Thanks for your help.
• Switching between tiers or migrating between two different SKUs is not supported until now in Azure Front Door, thus you will have to recreate the profiles accordingly as per the below documentation: -
https://learn.microsoft.com/en-us/azure/frontdoor/standard-premium/tier-comparison#feature-comparison-between-tiers
Also, do note that zero downtime migrations from Azure Front Door (Classic) to Azure Front Door (Premium) is in the roadmap for new feature improvement according to Microsoft. Thus, as you are trying to reconfigure the rule configuration in Azure Front Door (Premium) profile likewise that in Standard, I would suggest you refer the below snapshots for your understanding: -
Azure Front Door (Classic) rule configuration: -
Azure Front Door (Premium) rule configuration: -
• In the above screenshot, you want to configure route type as ‘Forward’ to the backend pool for ‘HTTPS’ requests as well as enable the URL rewrite in ‘Classic’ profile of Azure Front Door. To configure the similar rule in ‘Premium’ profile of Azure Front Door, please find the above screenshot. In that, to perform the similar functions accordingly, I have set the ‘Override origin group’ to ‘Yes’ which implies that the configuration specified in the Front Door endpoint route will be overrided by this rule set condition and will be forwarded to the origin group that you specify/select in the origin group. Along with it, since you have enabled the URL rewrite to be enabled in ‘Classic’ profile, you will have the privilege of mentioning the detailed ‘Source’ and ‘Destination’ path rewrites in ‘Premium’ profile of Azure Front Door.
Thus, ‘Premium’ profile of the Azure Front Door has more granular features compared to ‘Classic’ one and in this way, you can recreate the rule set in it. Also, find the below documentation link for more detailed understanding: -

I'm trying to migrate a Azure Linux/Python function app from the consumption tier to a Elastic Premium tier. It turns out this is not so easy: https://github.com/Azure/Azure-Functions/issues/155 . You basically have to recreate the Function from scratch.
As my function is sitting behind a APIM I thought it might be possible to do this by:
Creating a new ASP with the correct tier
Deploy Function into new ASP
Switch the APIM back end of the API to the new function.
The trouble is I can't figure out how to do that last part. I can't seem to find where this is configured, or how to change it (via the portal or via CLI).
I've even done some splunking in the configs using the new resources front-end https://resources.azure.com/ and can't even find where the APIM configuration for the backends reside.
You just need to go to your APIM, click "APIs" tab, choose your api under "All APIs", click "..." button of your api then import another function app to your APIM api.
For example, I have a api under "All APIs" in my APIM. Its backend is a function app running with consumption plan. Like below screenshot:
Now I want to change the backend of the api to another function app which running with Elastic Premium tier. Just click "..." button of the api, and click "Import" like below screenshot:
Then choose "Function App" and select your new function app.
I have an Azure webapp and normally if I want to block an IP address, I go to Azure dashboard panel and under networking>Configure Access Restrictions, I add a rule to do so. This picture shows which menu item I mean:
However, I would like to do this programmatically. I see that the documentation shows how you can do this through Powershell.
I have also managed to find the API documentation for WebApp. But I can't find the last piece of the puzzle which is the API that does what I need.
Can someone please tell me if it is possible and which API I should use? Thank you in advance.
According to the doc: Use an Azure REST API PUT operation on the app configuration in Azure Resource Manager. The location for this information in Azure Resource Manager is:
management.azure.com/subscriptions/subscription ID/resourceGroups/resource groups/providers/Microsoft.Web/sites/web app name/config/web?api-version=2020-06-01
Then I searched the Azure Rest API and found this:
PUT https://management.azure.com/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Web/sites/{name}/config/web?api-version=2019-08-01
We could update the field properties.ipSecurityRestrictions to update the value of Access Restrictions.
In addition, you could also check this blog: Bulk add IP Access Restrictions to Azure App Service using Az PowerShell
There does not appear to be a one-to-one match between powershell commands and api.
The closest I could find is:
https://learn.microsoft.com/en-us/rest/api/appservice/webapps/putprivateaccessvnet
This allows you to define which vnet has access to your web app. By controlling access to your vnet, you can control access to your app.
I am trying to use Azure Traffic Manager (GTM) to geographically distribute load to function apps in each region.
I have tried adding an 'app service endpoint' and an 'external endpoint' (including adding the GTM name as a custom CNAME to the function app), but both result in "Error 404 - Web app not found.". The custom CNAME also never adds correctly.
According to the last comment on this post, the ability to do this should now be supported:

Azure Traffic Manager is only eligible for use with App Services at the 'Standard' level or above as mentioned here. If your function isn't host in an app plan at the 'Standard' level or above, Azure Traffic Manager will not work.
If you are not using 'Standard' or higher level app plan, Azure Functions Proxies would be a workaround for you. Please check following thread which discuss the similar problem.
Azure Functions Traffic Manager
Here is the quick reference from the answer provided by Dakota Kincer.
So the answer I arrived to after Traffic manager didntsupport Azure functions was to overall build 3 Azure functions. I built an East and a West that has my azure function code on it. Then I built a main Azure Function that has 0 code. It only has Azure proxies on it that route to my 2 other Azure Functions. The route is controlled by a variable in the proxy string that is help in the main API app settings. Using %myvariable% you can set part of the url. When I need to publish I switch the variable to the secondary URL location. Update the Primary and then switch the URL to its original primary location. This will have to work for now till traffic manager is integrated into functions or a better solution arises.

You could modify your post if you want to provide more information.
Traffic Manager supports Azure functions monitoring. You can enable this by going to TM settings -> endpoints -> add endpoint -> choose Azure endpoint type -> App Service for Target resource type -> under Target Resource choose Function app which you want to monitor.
Most likely you want to be able to access function apps under specific domain domain, for example my-domain.com. For that under Custom Header Settings specify host:my-domain.com. You'll need to setup custom domain in function apps configuration too.
We have BizSpark subscription with shared app service plan, where we are hosting our product. I need to host another version of the project for testing purpose, which fits into a free tier. I have checked the azure portals, but there is no provision to add a new service plan. does the BizSpark subscription support only one app service plan or am I missing anything?
Because an App Service services is an underlying component to other services, there isn't a simple way to directly create an App Service.
Since the only use case to create an App Service is to put something in it, the logic (I imagine) behind the Portals is that you create the resources you require and and it will create dependent resources within that process.
(Using the New Portal)
In order to create a new App Service plan, presuming you are deploying a new Web App. Click on New, Web + Mobile and then Web App.
When you click on Web App you will get this screen, if you fill in the details, and click App Service plan / Location at the bottom, you will be given the opportunity to select either an existing App Service or to create a new one.
The easiest solution would be to create a new Web app and when asked for App Service create a new one .. or use Azure Resource Manager template to achieve this: https://azure.microsoft.com/en-gb/documentation/templates/.
If it's another version of the App for testing purposes, why not use Deployment Slots? Slots have their custom URL separate from the Production app, separated configuration, domain bindings, it's like an App inside an App. You'll be able (if you want) to even swap the content of the Production environment with the Testing one for example.
And you don't incur in any extra cost because it runs on the resources of the current App Service :)
