    2. There is no way for us to find the private IP assigned for the application gateway in the back end. Hence please improve this feature.

      There is no way for us to find the private IP assigned for the application gateway in the back end. Hence please improve this feature. Please have it enabled for the GUI, so that this can be use full to troubleshoot any network issues.

    3. application gateway monitor

      Application Gateways need more troubleshooting tools. The healthy/unhealthy logging is almost useless. We need to be able to initiate a ping/netcat from the AppGw to a host to verify connectivity. We also need to be able to see the DNS cache or see a log correlating incoming requests with outgoing requests by hostnames and IP addresses,

    4. Fully private App Gateway v2

      From: https://docs.microsoft.com/en-us/azure/application-gateway/migrate-v1-v2

      " v2 gateways currently don't support only private IP addresses."

      We need to be able to create fully private App Gateway V2, without public IP.

      At the moment V2 Gateways will be public facing so we need to stick with V1. We cannot rely on NSG/Firewall to restrict traffic: we need to be able to provision a private load balancer.

    5. Capability to apply WAF rules to each path rule.

      One of the customer wants capability to apply WAF rules to each path. Can you consider that?

    6. Allow control of the ARRAffinity set cookie response header

      Problem:
      When a request for contoso.com hits an Azure App Gateway and the back end is routed to contoso.azurewebsites.com, the set ARRAffinity cookie response includes the optional domain attribute (as per RFC6225 Page 22) that specifies "contoso.azurewebsites.net". causing the user agent to never write the cookie since the Domain attribute doesn't match the requested domain.

      Proposed Solutions:
      Solution #1
      Give us a way to disable the Set Cookie: domain attribute similar to the way we can add a "Arr-Disable-Session-Affinity" response header to disable the cookie entirely. I'm suggesting an "Arr-Disable-Session-Affinity-Strict-Domain" response header to tell the ARR proxy not to write…

    7. Allow creation of an empty application gateway

      (Following github issue https://github.com/Azure/azure-rest-api-specs/issues/2313)

      Hi,

      currently it is not possible to create an empty application gateway without frontend and backend configuration. so it is not possible to create an application gateway step by step.

      Could you allow the creation of an empty application gateway? then one could split the creation of an application gateway into multiple parts as requested in terraform-providers/terraform-provider-azurerm#727

      More details in the github issue

    8. Application Gateway handling the Query parameter on back-end

      In application gateway HTTP settings when we use "override back-end path" option, it is stripping out the query parameter and retains only the resource path.

      Eg: https://<<HostName>>:443/resurcepath/invoke?api-version=2016-10-01&number=5

      It retains only "https://<<HostName>>:443/resurcepath/invoke" and ignoring "?api-version=2016-10-01&number=5"

      It will be good to retain the query parameters without doing any URL redirection etc

    9. Retry policy for failed requests on Application Gateway

      To reduce the number of 502 bad gateway requests that are served up Application Gateway should have a retry policy for failed requests, allowing it to move the the next available server. This would be especially useful when used in front of Service Fabric where services are moved between servers.

    10. Support for temporary removing nodes through REST API

      It would be great if there was a REST API or something similar we could use to take a node out of rotation without being dependent on the probe detecting it.

      Usecase: We run SF behind the Application Gateway. When we update our front-end service, we would like to take it out of rotation before the service is updated. This does not seem possible today, since we have to rely on the probe detecting that a node has gone down. Since the probes have a lag (it probes on a given interval), some users will have a bad experience when…

    11. Add X-Forwarded-For information in Application Gateway Access log

      If we have other Layer 7 Load Balancer like Cloudflare load balancer uses in front of AppGw, we are not able to obtain real client IP. Imagine Cloudflare load balancer inserts X-Forwarded-For info before forwarding request to AppGw, can we add X-Forwarded-For information in Application Gateway Access log?

    12. Application Gateway v2: Cannot be working correctly when the "Test" button on setting custom probes with using the "Health probes".

      We deployed the Application Gateway v2 on Azure Portal to set the custom probe configuration using the "Health probes",
      And push the "Test" button. In the result, we got just only the message "No Result.".
      It must be appeared backend instances on the display.
      However, it seems not to check backend pool instances health correctly on Azure Portal.
      Please fix this "Test" function with working correctly on Azure Portal.

      Test backend health with the probe:
      https://docs.microsoft.com/en-us/azure/application-gateway/application-gateway-create-probe-portal#test-backend-health-with-the-probe

    13. Pathbased rules are case sensitive for WAF_v2

      Hello,
      It seems as the 'Paths' of Pathbased rules of Azure Application Gateway with tier 'WAF_v2' are case sensitive.

      f.eks: when pathbased rule path is /foo, only 'http://gatwaydns:port/foo&#39; will fire that path rule while 'http://gatwaydns:port/Foo&#39; will not.

      this can become blocking if there exist multiple clients where case sensitivity has not been of consirn.

      Please fix.
      Thanks.

    14. Application Gateway v2 "trusted root certificate" configuration via portal

      To configure end-to-end encryption with Application Gateway v2, cer is not supported for Backend Authentication Certificates under the HTTP settings. Using this will result in an error stating authentication certificates are not supported for v2. A Trusted Root Certificate should be configured for v2. This option seems to only be availalbe via powershell and not through the Azure Portal.
      Please update the portal configuration options under "Add HTTP Setting" to allow adding Trusted Root for v2 gateways and not just Authentication Cert.

    15. Allow IP range whitelist for Application Gateway WAF IPS/IDS

      We have a range of web apps behind an Application Gateway (WAF in IPS mode) that need to be scanned on at least monthly basis for PCI compliance. We need to be able to whitelist the range of the scanners used by Qualys otherwise we get a FAIL for "Possible Scan Interference".

      Threat:
      Possible scan interference detected.

      A PCI scan must be allowed to perform scanning without interference from intrusion detection systems or intrusion prevention systems.
      The PCI ASV is required to post fail if scan interference is detected.

    16. Add custom error pages like 405(with TRACE method) at global level of application gateway V2

      Please add custom error pages like 405(with TRACE method) and other status code returned by appgw(without forwarding request to backend) at global level of application gateway V2, where customer can block other scenarios and return a designated URL to original client.
      Sometime customer has a requirement of completely removing 'Microsoft-Azure-Application-Gateway/v2' in response header, so please consider to add this feature in future.

    17. Application Gateway, App Service and ARRAffinity

      We are trying to route all our app service traffic through application gateway.

      We have the apservice running on multiple instances and arraffinity is enabled on the appservice

      When we route the traffic through applicationgateway i note that the arraffinity cookie is being removed, as such user sessions switch across appservice instances and our application does nto work correctly

      I tried enabling session affinity on the http setting but it still doesnt work

      What is the correct setup to allow app gateway to be used with appservice and arraffinity

    18. Allow public and private ip to have its own listener on the same port

      single gateway would support both public and private ip but the not able to create the two listeners for public and private on the same port. it would be great to have this feature else we need to create 2 application gateway for this purpose which defeats the purpose of public and private front end configurations to some extent.
