-When the following conditions are met, the version `version: gray` will be used:
- `userid` in the cookie equals `00000002` or `00000003`
- Users whose `level` in the cookie equals `level3` or `level5`

-`{version}` will be dynamically replaced with the actual version during execution.
-
-#### indexRouting: Homepage Route Configuration
-Accessing `/app1`, `/app123`, `/app1/index.html`, `/app1/xxx`, `/xxxx` will route to '/mfe/app1/{version}/index.html'.
-
-#### fileRouting: File Route Configuration
-The following file mappings are effective:
- `/js/a.js` => `/mfe/app1/v1.0.0/js/a.js`
- `/js/template/a.js` => `/mfe/app1/v1.0.0/js/template/a.js`
- `/app1/js/a.js` => `/mfe/app1/v1.0.0/js/a.js`
