Motivation

Hi,

I'd like to use the new abort_request API: https://github.com/sgl-project/sglang/blob/58f10679e1850fdc86046057c23bac5193156de9/python/sglang/srt/entrypoints/http_server.py#L549

However, I'm using multiple SGLang servers behind a router, and currently the router doesn't seem to support abort_request: https://github.com/sgl-project/sglang/blob/main/sgl-router/src/server.rs

I'm wondering if it makes sense to also support abort_request in the router. Thanks!

Research direction
Study the existing router source code in sgl router/src/server.rs to understand how requests are routed and how to add a new abort endpoint that forwards to the appropriate backend server.
