Bug Description

When starting sglang in HTTP mode, accessing the default root endpoint (http://<ip>:<port>/) returns the message:

Ollama is running

This is misleading and appears to be an incorrect response for an sglang server. Users may be confused because the response suggests that an Ollama service is running instead of sglang.

Steps to Reproduce

1. Start sglang using HTTP mode.
2. Open a browser or use curl to access the root endpoint:

http://<ip>:<port>/

3. Observe the returned response.

Actual Behavior

The server responds with:

Ollama is running

Expected Behavior

The endpoint should either:

• Return an sglang-specific message (e.g., sglang server is running), or
• Return a proper API root response / documentation endpoint.

Notes

This response likely comes from a reused or inherited handler and does not reflect the actual running service, which may lead to confusion during debugging or service verification.
