## Test Coverage

The project includes comprehensive unit tests for all core components:
- `CurlTest`: Tests for static factory methods and basic HTTP operations
- `CurlRequestTest`: Tests for request builder, headers, parameters, body content, SSL, proxies, timeouts
- `CurlResponseTest`: Tests for response handling, status codes, content retrieval, resource management

Caching
=======

OkHttp implements an optional, off by default, Cache. OkHttp aims for RFC correct and
pragmatic caching behaviour, following common real-world browser like Firefox/Chrome and 
server behaviour when ambiguous.

# Basic Usage

```kotlin
  private val client: OkHttpClient = OkHttpClient.Builder()
      .cache(Cache(
          directory = File(application.cacheDir, "http_cache"),
          // $0.05 worth of phone storage in 2020

        sourceMap.put(field, value);
    }

    // ===================================================================================
    //                                                                      Basic Override
    //                                                                      ==============
    @Override
    protected String doBuildColumnString(String dm) {
        StringBuilder sb = new StringBuilder();

            Class.forName("com.ibm.disni.RdmaActiveEndpointGroup");

            // Additional checks could include:
            // - Verifying RDMA devices are available
            // - Testing basic RDMA operations
            // - Checking for required native libraries

            return true;
        } catch (ClassNotFoundException e) {
            log.debug("DiSNI not available: {}", e.getMessage());
