+Other than editing routing in the web UI, you can also create a config file and let Zoraxy load it on startup. You can put your config file under ```conf/proxy/``` as JSON file with file extension ".config". For example, here is an example of `(ST).test.localhost.config`
+
+**This config structure is for Zoraxy v3 only**
+```json
+{
+ "ProxyType": 1,
+ "RootOrMatchingDomain": "*.test.yourdomain.com",
+ "Domain": "192.168.1.100:8080",
+ "RequireTLS": false,
+ "BypassGlobalTLS": true,
+ "SkipCertValidations": true,
+ "VirtualDirectories": [
+  {
+   "MatchingPath": "/example/",
+   "Domain": "example.com",
+   "RequireTLS": true,
+   "SkipCertValidations": false,
+   "Disabled": false
+  },
+  {
+   "MatchingPath": "/teacat/",
+   "Domain": "sorae.co",
+   "RequireTLS": true,
+   "SkipCertValidations": false,
+   "Disabled": false
+  }
+ ],
+ "UserDefinedHeaders": [
+  {
+   "Key": "X-Special-Header",
+   "Value": "foo=bar"
+  }
+ ],
+ "RequireBasicAuth": false,
+ "BasicAuthCredentials": [
+  {
+   "Username": "USERNAME",
+   "PasswordHash": "PASSWORD_HASH_HERE"
+  }
+ ],
+ "BasicAuthExceptionRules": [
+  {
+   "PathPrefix": "/public/api/"
+  }
+ ],
+ "DefaultSiteOption": 0,
+ "DefaultSiteValue": "",
+ "Disabled": false
+}
+```
+
+Here is another example that is use for default site (previously named Proxy Root). The file must be named as `root.config`
+
+```json
+{
+ "ProxyType": 0,
+ "RootOrMatchingDomain": "/",
+ "Domain": "imuslab.com",
+ "RequireTLS": true,
+ "BypassGlobalTLS": false,
+ "SkipCertValidations": false,
+ "VirtualDirectories": null,
+ "RequireBasicAuth": false,
+ "BasicAuthCredentials": null,
+ "BasicAuthExceptionRules": null,
+ "DefaultSiteOption": 1,
+ "DefaultSiteValue": "imuslab.com",
+ "Disabled": false
+}
+```
+Here are some key items for the proxy config
+- ProxyType: 0 = root and 1 = host. For root, name your config file root.config
+- RootOrMatchingDomain: Matching rules or keywords, use `/` for default site router
+- Domain: Proxy target / backend
+- RequireTLS: Proxy target require TLS (https) connection
+- BypassGlobalTLS: Allow this rules to be accessed via port 80 endpoint (if enabled)
+- SkipCertValidations: Skip proxy target TLS error, for self sign certificate
