    1. Need a function to disable the timestamp in TCP option in Application Gateway

      In some cases, the timestamp in TCP option is concerned about a security risk.

      So I want a function to make it disable in Application Gateway.

      TCP option is the setting in OS layer, so it may need a change in OS for Application Gateway.

    2. Reduce update times for Application Gateways

      It would be great if the Application Gateway could update faster. Working with AGWs forces me to wait for 15-30 minutes after each update - which wastes a lot of time.

      Working with gateways at AWS feels nearly instant and does not require such long waiting times.
      I'd highly appreciate if Azure AWG updates could become so fast, too.

    3. Direct Traffic to External web page when all nodes in a pool are down

      Ability to redirect incoming request to external webpage when all nodes in the backends pool are shutdown. Users will get this information information during maintenance/outage.

    4. Let's Encrypt Integration for HTTPS certificates

      It should be possible to define a list of SSL hostnames. Application Gateway should automatically acquire and renew certificates for all given hostnames (most probably through the HTTP domain validation process).

      For every request, Application Gateway should use the correct certificate based on the hostname.

      Supporting multiple hostnames is critical to use Let's Encrypt with multi-site routing.

    5. Add more metrics to better analyse capacity, firewall violations, etc

      Analysis via Log Analytics is useful, but it'd be nice to have some predefined reports or "blades" in Azure Portal to analyse events, throughput, capacity/utilization.

    6. Make default ssl settings more secure (https://www.ssllabs.com gives only B-rate).

      When we deploy SSL listener with default settings, ssl configuration in not very secure (although acceptable for some services). Popular checker https://www.ssllabs.com gives just B-rate for this. You can check recommendations for example looking at report for our sample AGW deployed with default settings https://www.ssllabs.com/ssltest/analyze.html?d=tb-ag-dev.textback.io

    7. Need more information from Log Analytics for App Gateway.

      We see 400 errors in Log Analytics. We don't see these connections on the web servers. We think the App gateway is dropping traffic. Support doesnt seem to know why this happens. We don't have enough good information to track these issues. requestQuery_s is blank, MS support cannot tell me what this is, let alone what it means if it is blank.
      We need more information.

    8. support ESI (Edge Side Includes) in the Application Gateway and CDN like Vanish or Akamai.

      ESI can be a great feature for server side content based integration ( transclude of html fragments ) in a microservice architecture. For more information please read : ( https://gustafnk.github.io/microservice-websites/#integrating-on-content ).

    9. 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…

    10. WAF on Application Gateway needs a function to exclude some condition like a trusted node.

      Now, Web Application Firewall feature would be available as part of Azure Application Gateway.

      Currently, WAF on Application Gateway seems to not have a function to exclude from blocking access by any condition.
      So, I would like to request to add this function for WAF on Application Gateway.

      Acutually, Many WAF product could exclude particular access from blocking like a trusted node.

      Thanks for the valid suggestion. Your feedback is now open for the user community to upvote which allows us to effectively prioritize your request against our existing feature list and also gives us insight into the potential impact of implementing the suggested feature

    11. 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.

    12. Backend heath status of Application Gateway

      We deployed the Application Gateway on the subnet where NSG's In-Bound rules is set. In the result, we got the status of backend health is 'unknown'. We got the 'Healthy' status when the NSG doesn't associate to subnet. Even if NSG's In-Bound rules is set, We'd like to confirm the backend health.

    13. Add MTOM support to the Microsoft WAF

      We currently have a use case for utilizing MTOM to more efficiently transmit binary data in a SOAP-based service.

      We are also trying to place the application behind a Microsoft WAF in Azure, but are unable to do so due with the WAF in prevention mode as the WAF does not currently support/allow MTOM requests.

      We reached out to Azure support and were told that:

      "MTOM is not supported and it's not yet on implementations plans".

      We are requesting that the Microsoft WAF team add support for making MTOM calls to a service that go through the WAF.

    14. Application Gateway WAF needs function.

      Application Gateway WAF hasn't function creating custom rules and operating management UI for regular or custom rules. Also, we hope functional enhancement for WAF logs. We'd like to get the detail message if alert is happen.

      Thank you for your time and consideration.

    15. Support traffic fork/shadowing/mirror on application gateway.

      Support traffic fork/shadowing/mirror on application gateway. Sometimes we need send shadow traffic to a testing/staging environment, and the best place to do this is layer 7 load balancer..

    16. Support URL rewriting with Application Gateway

      PathBasedRouting is nice, but not super great without the ability to rewrite paths. I am trying to front a Service Fabric cluster, where multiple HTTP services live on http://+:80, at different path prefixes. Would be nice to use Application Gateway to direct https://api.company.com to http://cluster/api, and https://www.company.com to http://cluster/www

    18. Show domain in logs

      The access logs for the application gateway only show the routes. We use a single gateway to host multiple sites and some have similar folder structures, this makes evaluating access and tracing issues a bit difficult. It would be great if the actual domain (http://www.something.com) was listed in there too.

    20. Insight in Azure application gateway performance

      Currently there is no way to view usage statistics of the Azure application gateway. Information I would like to see:


      • Per hour performance statistics (e.g. nr of connections, bandwith, CPU usage, etc.)

      • Advice on number of required instances based on metrics from last few days with recommendations to increase or decrease the number of instances

      Regards,

      Jan-Willem
