Support for HTTP/2 Protocol in ArcGIS Enterprise

[Felipe_Costa]

Hello everyone,

I’d like to ask if anyone has experience with enabling or configuring HTTP/2 for ArcGIS Enterprise (Portal, ArcGIS Server, and related components). Does ArcGIS Enterprise natively support HTTP/2, or does it depend entirely on the web server/reverse proxy (e.g., IIS, or Apache)?

We received a request from our security team to check "HTTP/1.1 request smuggling vulnerabilty" within ArcGIS Enterprise components.

We are considering enabling HTTP/2 in our environment to optimize client connections and would and minimize the risk of attacks, and appreciate any insights or experiences from the community, but I did no find how to implement it on ArcGIS Server and Portal so far.

Thanks in advance!

Hi @Felipe_Costa, That is tricky, I have never tried such thing, but I believe ArcGIS Enterprise itself does not currently support HTTP/2 directly, it's limited to HTTP/1.1. To enable HTTP/2 I guess you could configure it at the web adaptor in IIS /reverse proxy layer.
