Hello @SaladiVaraprasad-1079 Thank you for your question, I see a similar question from this link: https://learn.microsoft.com/en-us/answers/questions/661249/enable-gzip-compression-in-azure-application-gatew

here AGIC on AKS is managed by add-ons, and any change on the configurations will be un-supported on AGIC configurations, for manual changes you can use the Azure Application gateway, but to achieve that by your responsibility to enable g-zip on AGIC,you can try it on a test AGIC with AKS as below: 1- Run the following command to edit the AGIC configuration file:

kubectl edit configmap agic-config -n kube-system

2- Add the following lines to the data section of the configuration file: enable-compression: "true" compression-type: "gzip" 3- Save and exit the configuration file. 4- Restart the AGIC pod by running the following command: kubectl delete pod -n kube-system -l app=agic 5- Verify that Gzip compression is enabled by checking the response headers of a request to your application. Please note that enabling Gzip compression may increase CPU usage on the Application Gateway Ingress Controller Hope this helps.

Hello @SaladiVaraprasad-1079

here you also need to enable it on the application level hosted on AKS, depending on your application, and you need to check how to enable it inside the application,

for example, nginx application you can enable it from the nginx.conf

and add gzip on

as you are working on 3rd party application you have to check with their community how to enable it.

Thank you!
