由Caddy做SNI分流，REALITY(别人的网站) 和自建网站共存配置问题探讨。

我根据Xray(E+F+H+G+B+A)+Caddy(N)的模板修改了一个reality指向itunes（xray在5443口），同时服务器上还挂着一个网址是sub.mydomain.com的站（服务在8080口）。脱敏的全配置如下：

{
	"admin": {
		"disabled": true
	},
	"logging": {
		"logs": {
			"default": {
				"writer": {
					"filename": "/etc/caddy/error.log",
					"output": "file"
				},
				"encoder": {"format": "console"},
				"level": "error",
				"exclude": ["http.log.access.log0"]
			},
			"log0": {
				"writer": {
					"filename": "/etc/caddy/access.log",
					"output": "file"
				},
				"encoder": {
					"format": "transform",
					"template": "{common_log}"
				},
				"include": ["http.log.access.log0"]
			}
		}
	},
	"apps": {
		"layer4": {
            "servers": {
                "sni": {
                    "listen": [":443"],
                    "routes": [{
                        "match": [{"tls": {"sni": ["itunes.apple.com"]}}],
                        "handle": [{
                            "handler": "proxy",
                            "upstreams": [{"dial": ["127.0.0.1:5443"]}],
                            "proxy_protocol": "v2"
                        }]
                    }]
                }
            }
        },
		"http": {
			"https_port": 443,
			"servers": {
				"srv0": {
					"listen": [":443"],
					"routes": [{
						"match": [{"host": ["*.mydomain.com"]}],
						"handle": [{
							"handler": "subroute",
							"routes": [
								{
									"handle": [{
										"encodings": {"gzip": {},"zstd": {}},
										"handler": "encode",
										"prefer": ["gzip","zstd"]
									}]
								},
								{
									"handle": [{
										"handler": "subroute",
										"routes": [
											{
												"handle": [{
													"handler": "reverse_proxy",
													"upstreams": [{"dial": "127.0.0.1:8080"}]
												}]
											}
										]
									}],
									"match": [{"host": ["sub.mydomain.com"]}]
								}
							]
						}],
						"terminal": true
					}],
					"logs": {"logger_names": {"*.mydomain.com": ["log0"]}}
				}
			}
		},
		"tls": {
			"automation": {
				"policies": [{
					"subjects": ["*.mydomain.com"],
					"issuers": [
						{
							"challenges": {
								"dns": {
									"provider": {
										"api_token": "my_api_token",
										"name": "cloudflare"
									}
								},
								"tls-alpn": {"alternate_port": 443}
							},
							"email": "my@email.com",
							"module": "acme"
						},
						{
							"ca": "https://acme.zerossl.com/v2/DV90",
							"challenges": {
								"dns": {
									"provider": {
										"api_token": "my_api_token",
										"name": "cloudflare"
									}
								},
								"tls-alpn": {"alternate_port": 443}
							},
							"email": "my@email.com",
							"module": "acme"
						}
					]
				}]
			}
		}
	}
}

搓出来的确能跑，通配符正常拿到手，梯子也是通的，但是网站时不时会加载不出来部分元素导致显示异常。请求指教该配置是否存在问题如何调整？

你参考对象弄错了！你应该以Xray(M+F+H+K+G+B+A)+Caddy(N) 示例进行修改，REALITY 所需证书改为别人的网站提供，通步修改 SNI 分流，其它应用删除仅保你需要的即可。

[JKSTAFF]

上面的实验性配置就是修改自Xray(E+F+H+G+B+A)+Caddy(N)。我未能在其中找到将 REALITY 所需证书改为外部网站提供 的样例，同时我也需要为服务器上的自建站保留自己的证书。您可以再多给一些提示吗。

晕，以 Xray(M+F+H+K+G+B+A)+Caddy(N) 示例修改！Xray 配置中 7443 端口及域名等改为别人的网站域名，具体参考对应单一示例。 另外 SNI 分流配置中对应 REALITY 域名改为别人的网站域名。
