Hi, according to this [post]( Azure Front Door doesn't support SSE.

What about Application Gateway? Can we use it for SSE?

    Thank you for your patience here. I got a response back from the team.

    Currently Azure Application Gateway does not support server-sent events (SSE) but the support will be added in future, currently we do not have an ETA.

    Although we have some validations you may try, please let me know if you are interested in trying the changes out and providing feedback if it meets your requirements.

    Hope this helps! Please let me know if you have any additional questions. Thank you!

    Hello @ChaitanyaNaykodi-MSFT

    we have a similar issue regarding the Azure Application Gateways SSE support ... at the moment we are using the Azure Application Gateway v1 wich supports SSE at the moment but v1 will be retired on 28 April 2026 so do you have more information when the SSE support will be integrated in v2 or is there already a Azure Gateway beta version available with SSE support which can be tested?
