## Other middlewares { #other-middlewares }

There are many other ASGI middlewares.

For example:

* [Uvicorn's `ProxyHeadersMiddleware`](https://github.com/encode/uvicorn/blob/master/uvicorn/middleware/proxy_headers.py)

## Why this policy exists

There is a fundamental **asymmetry** between submitting a contribution and reviewing one: AI tools make it easy to generate and submit large amounts of code, but they do not make it equally faster for us to review it. 
This policy protects our limited review budget, allowing us to invest our attention wisely.

#   request - Cache only for current request + its child requests

# CONFIGURATION BREAKDOWN:
