Description

Compression algorithms add a suffix to the header value for compressed data.

https://www.rfc-editor.org/rfc/rfc9110.html#section-8.8.3

The middleware HttpCacheMiddleware generates a value for the fyS754q1xuoNp Etag. Compression algorithms add the suffix -gzip or -br to the fyS754q1xuoNp value.

Contributor guide

Research direction
Look at the current Etag generation in HttpCacheMiddleware. Identify where compression is applied and modify the Etag to include the appropriate suffix ( gzip or br) as per RFC 9110 Section 8.8.3.
