ASGI
Asynchronous Server Gateway Interface, a specification in the Python web ecosystem that implements high-concurrency processing based on the asyncio event loop. It supports WebSocket and SSE streaming, and is a mainstream deployment standard for enterprise-grade AI application backends.
Core Facts
FastAPI is built on Starlette and Pydantic, natively supports asynchronous processing, and is based on ASGI (Asynchronous Server Gateway Interface).
Starlette is a lightweight Python asynchronous web framework/toolkit developed by Tom Christie, built on top of the ASGI standard.
ASGI is the asynchronous successor to WSGI; based on Python's async/await syntax, it allows a single process to concurrently handle thousands of connections.
Timeline (last 90 days)
Checking only for Brotli calls in business code is insufficient; it is also necessary to confirm whether framework versions, reverse proxies (such as Nginx and Envoy) and WSGI/ASGI servers are affected, and to evaluate mitigation measures such as disabling unnecessary compression encodings or limiting request body size.
Vercel routing middleware can run as a standalone ASGI or WSGI application, executing before requests enter the main application.
A WSGI application is a callable object app(environ, start_response), while an ASGI application is async def app(scope, receive, send).
WSGI (Web Server Gateway Interface, PEP 3333) is a synchronous standard, on which Django and Flask are built by default; ASGI is the asynchronous evolution, supporting async/await, WebSocket, and long-lived connections, and is used by FastAPI and Starlette.
Deploying agents into an ASGI service in enterprise environments is standard practice, mainly because it needs to support high-concurrency request handling and true streaming output.
The agents in the project access supplier websites via crawlers or APIs to scrape quote information, forming a chain of "running inside the sandbox → MCP gateway reading ERP → crawler fetching quotes → multi-model collaboration → ASGI streaming return".
CGI is the earliest general interface specification but has been basically phased out due to poor performance; WSGI is an optimized version built on it but only supports synchronous operation, while ASGI goes a step further by supporting asynchronous development.
New versions of Flask have begun to support ASGI, and the performance gap between FastAPI and Flask may narrow in the future, but the advantages of asynchronous architecture in high-concurrency scenarios will still remain.
ASGI has become the standard choice for agent deployment primarily by addressing two core issues: high-concurrency asynchronous processing and streaming output.
This project uses uvicorn as the ASGI server to deploy the agent.
