Example Code

uvicorn rest.main:server --host 0.0.0.0 --port 8080 --reload --root-path /proxy

server = FastAPI()

# separate spec at /v1/docs
server.mount("/v1", app_v1)
# separate spec at /v2/docs
server.mount("/v2", app_v2)

#where app_v1, app_v2 is like below
app_v1 = FastAPI(openapi_tags=tags_metadata, title="Pet store")

Description

When I run the uvicorn with the --root-path option for the above setup, the server is expecting that I include the defined root path in every request e.g:
http://localhost:8080/v2/docs is not working (404)
http://localhost:8080/proxy/v2/docs is working

IN version 0.108.0 It works as described here https://fastapi.tiangolo.com/advanced/behind-a-proxy/
