## Patterns

### IIS URL Rewrite Rules for SPA with Multiple API Backends
**Discovered**: 2025-12-22 (feature: unified-app)
**Description**: Configure IIS web.config to proxy different API paths to different backend ports while serving SPA for all other routes. Enables single IIS site to route to multiple microservices.

**Example** (`public/web.config:5-28`):
```xml
<rewrite>
  <rules>
    <rule name="Proxy Reports API" stopProcessing="true">
      <match url="^api/reports/(.*)" />
      <action type="Rewrite" url="http://localhost:8001/api/{R:1}" />
    </rule>
    <rule name="Proxy Data Entry API" stopProcessing="true">
      <match url="^api/data-entry/(.*)" />
      <action type="Rewrite" url="http://localhost:8003/api/{R:1}" />
    </rule>
    <rule name="SPA Fallback" stopProcessing="true">
      <match url=".*" />
      <conditions logicalGrouping="MatchAll">
        <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
      </conditions>
      <action type="Rewrite" url="/index.html" />
    </rule>
  </rules>
</rewrite>
```
