custom HttpClient each route.

Before I start, I will apologize for my terrible English and start.

I want to create and apply a custom HttpClient for each route. For example, the timeout setting is set to 10 seconds for route1 and the timeout setting is set to 30 seconds for route2.

Please refer to the code below as a solution to the function.
I defined a CustomNettyRoutingFilter that inherits NettyRoutingFilter and redefined the getHttpClient() function so that if there is a newly defined ttpClient in exchange.getAttributes(), it can be returned.

@Component
public class CustomNettyRoutingFilter extends NettyRoutingFilter {
    public CustomNettyRoutingFilter(HttpClient httpClient, ObjectProvider<List<HttpHeadersFilter>> headersFiltersProvider, HttpClientProperties properties) {
        super(httpClient, headersFiltersProvider, properties);
    }

    @Override
    protected HttpClient getHttpClient(Route route, ServerWebExchange exchange) {

        if (exchange.getAttributes(). containsKey("httpClient")) {
            return (HttpClient)exchange.getAttributes().get("httpClient");
        }

        return super.getHttpClient(route, exchange);
    }
}

and then used filters to create and inject the desired HTTP client for each route into exchange.getAttributes().
I want to know if the code I designed is on the right track.

Start with spring-cloud-gateway-server/src/main/java/org/springframework/cloud/gateway/filter/NettyRoutingFilter.java and inspect how the route and ServerWebExchange are used. Evaluate the proposed CustomNettyRoutingFilter and exchange attribute approach against the gateway's existing filter behavior; done means a clear, documented conclusion about whether route-specific HttpClient selection is supported.
