    /**
     * Adds a client with a regular expression pattern.
     * @param regex The regular expression to match URLs.
     * @param client The CrawlerClient instance.
     */
    public void addClient(final String regex, final CrawlerClient client) {
        if (StringUtil.isBlank(regex)) {
            throw new CrawlerSystemException(

		<postConstruct name="addClient">
			<arg>["http:.*", "https:.*"]</arg>
			<arg>httpClient</arg>
		</postConstruct>

}
```

2. **Register in DI config** (`crawler.xml`):
```xml
<component name="myClient" class="...MyClient" instance="singleton"/>
```

3. **Add to factory**:
```java
clientFactory.addClient("^myprotocol://.*", myClient);
```

4. **Add tests**: Unit + integration

### Adding a Content Extractor

1. **Implement `Extractor`**:
```java
public class MyExtractor extends AbstractExtractor {

                .<CrawlerClientFactory> singleton("clientFactory", CrawlerClientFactory.class, factory -> {
                    factory.addClient("http:.*", container.getComponent("httpClient"));
                    factory.addClient("file:.*", container.getComponent("fsClient"));
                })
                .singleton("tikaExtractor", TikaExtractor.class)

		}
	}

	addedCount := 0
	var (
		peerAddErr error
		admClient  *madmin.AdminClient
	)

	for _, v := range sites {
		if v.self {
			continue
		}
		switch {
		case currDeploymentIDsSet.Contains(v.DeploymentID):
			admClient, err = c.getAdminClient(ctx, v.DeploymentID)
		default:
			admClient, err = getAdminClient(v.Endpoint, v.AccessKey, v.SecretKey)
		}
		if err != nil {
