    1. WAF file size limit to be increased

      Currently as the WAF limit is set to 100mb, we cannot process our large files which could hit 500mb for example.

      Can you please increase the WAF file silze limit? To possibly 1GB / 2GB

    2. Add a way to test the configuration of Application Gateway before update

      When updating an application gateway (example changing to a different backend). It would be useful to be able to test the configuration of the application gateway before saving.

    3. 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

    4. Application Gateway WAF: update to OWASP CRS 3.0.2

      The 'OWASP 3.0' (3.0.0) WAF rule set generates a lot of false positives, even on random base64 payloads. The only option is to disable many rules.

      2 examples which frequently trigger on SAML authentication exchanges are 932140 (https://github.com/SpiderLabs/owasp-modsecurity-crs/issues/671) and 941120 (https://github.com/SpiderLabs/owasp-modsecurity-crs/issues/675).

      OWASP CRS 3.0.2 reworked some rules, in order to reduce some of these false positives. Please support CRS 3.0.2 (either as an in-place upgrade for 3.0.0, or as a new option).

    5. Maximum Internet Traffic supported by Application Gateway . Sometimes there will be a performance test conducted . So it is better to know

      Would be great if there is some information on the maximum traffic supported by Application gateway

    7. Azure Application gateway - Allowed concurrent connection

      1) Tier - WAF , SKU Size - medium

      2) Tier - WAF , SKU Size - large

      3) Tier - Standard , SKU Size - small

      4) Tier - Standard , SKU Size - medium

      5) Tier - Standard , SKU Size - large

      Example: If I'm using WAF with Medium SKU and 8 Instances what will be my limit of concurrent connections.

      Thanks,
      Gulab Pasha

    8. URL path management

      It would be nice to have ability to allow/block some path of the hosted sites:
      /page1/subpage1/subpage2 - allow
      /page1/subpage1 - block
      / - block
      or at least to allow/block only one page.

    9. Sort Application Gateway Rules alphabetically

      My lists of Application Gateway Rules / Listeners and HTTP Settings is growing very fast. I've applied a naming convention but the lists are in random order so it's hard to find the settings which are for the same customer.

    10. Reorder the Listeners on the Application Gateway

      Recently I was in the need to register additional listeners to an App Gateway. The issue is that the rules and Listeners should be created (at least using the portal) on correct order and the portal don't have any options to change this order.
      As the process of update changes on the Gateway takes a few minutes, this type of change requires a few hours to create a new record, remove, add it again, create rules, etc.
      Using a pattern similar to the NSG where we define a value for the order would save a lot of time.

    11. Application Gateway: Support wildcard hosts in listeners

      Our product creates dynamic DNS zones for our customers, e.g. foo.z1.contoso.com, bar.z2.contoso.com, etc. We use Azure DNS for this. (Notice that we stripe our customer's domains across multiple zones (z1, z2), because Azure DNS has a max record count of 5000.)

      So, to support this, we have a wildcard SSL certificate for each zone e.g. .z1.contoso.com, .z2.contoso.com.

      In order to have Application Gateway provide SSL termintation for us, we obviously need to create Multi-site listeners for port 443. Unfortuantely, the 'Host' field on the Multi-site listener does not accept wildcard entries. Furthermore, specifying the host name 'z1.contoso.com' does not appear…

    12. More granular backend pool monitoring

      The App Gateway as it stands only allows you to monitor the overall (every member of every pool) backend pool health. It does not allow you to alert on a specific backend. One pool may be healthy with one member down and another may be unhealthy with one member down.

    13. Allow paths in Application Gateway rules to be defined as regular expression

      Currently, Application Gateway rules support only path matches with a wildcard at the end of the string.

      For us it means to rework our routing strategy as the first part of our route is dynamic /<domain>/<controller> (eg. /sales/process). The controllers are shared among domains. Domains can be dynamically created, what disallow us to directly use the current feature to separate only 'process' controller to standalone backend pool.

      We would prefer to be able to define something like '/[a-z]]+/process.*' as a matching criterion.

    14. Application Gateway WAF: need the ability to adjust rule 911100 list of methods

      API management allows additional methods such as PATCH, PUT, DELETE and TRACE which some companies use in their API's.

      The default WAF list under rule 911100 is GET HEAD POST OPTIONS which is not sufficient and leads to the disabling of the rule in the application gateway WAF in front of API Management.

    15. Accept request only from specific source IP address

      I'm raising this again as the original from someone else was declined, possibly due to lack of clarity on purpose.

      On an app gateway that has multiple listeners, there might be a need for listener A to be accessible from IP x and listener B to be accessible from IP y.

      Using an NSG, only the whole of the App Gateway can have rules associated with it. I can't have listener A accept from one IP and listener B from another as listeners do not have a distinct identity that can be referenced in an NSG.

      The only way around…

    16. Forward Request's Original Host

      This is useful when backend services need a way to recognize the client's requested domain (i.e. multitenant saas based on custom domains).

      X-Forwarded-Host or other custom header where we can get the original domain's name.

      Thanks!

    17. Current CPU Utilization metrics

      We've 502 failed request. Upon raising a ticket with Microsoft support we found that the Instance count was getting heavily utilized. Can you implement CPU Metrics so that we can do the same thing by ourselves.

    18. Support for EC Elliptic Curve Customization

      Azure Application Gateway custom SSL policies don't seem to allow the customization of the elliptic curves to use like we normally do on Windows Server 2016 for example (via PowerShell "enable-TlsEccCurve" for example). I believe this extra customization option would very useful for specific integration scenarios.

      Thank you,

    19. Feature request: Changing idle timeout for Application Gateway with private IP address.

      Currently we can specify timeout only to a public IP address of Application Gateway. But we can’t change the timeout of a private IP of Application Gateway. Can you add a new feature to allow us to specify timeout for private IP address too.

    20. Delete the listener but rule will be left and invisible

      After delete the listener, the rule still left and you can't see them in the UI. When you create the rule with same name, the request will be denied. You can see the left rules in the resource explorer.
