+## Rewrite for getEnvConfig
+
+Please add the following rewrite rules to your `Web.config` file to redirect requests for `getEnvConfig` to `dynamic-env.json`, See [Angular RemoteEnvironment](https://abp.io/docs/latest/framework/ui/angular/environment#remoteenvironment) for more details.
+
+```xml
+<?xml version="1.0" encoding="utf-8"?>
+<configuration>
+<system.webServer>
+ <rewrite>
+  <rules>
+    <rule name="Redirect" stopProcessing="true">
+      <match url="getEnvConfig" />
+      <action type="Redirect" url="dynamic-env.json" />
+    </rule>
+    <rule name="Angular Routes" stopProcessing="true">
+      <match url=".*" />
+      <conditions logicalGrouping="MatchAll">
+        <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
+        <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
