- **`CurlException`**: Unchecked RuntimeException for HTTP errors.

### I/O Layer

- **`ContentCache`**: In-memory or file-based caching. Implements `Closeable` and auto-deletes file cache on close.

- **`ContentOutputStream`**: Extends `DeferredFileOutputStream`. Writes to memory until threshold (default 1MB) exceeded, then spills to temp file.

## Technical Details

- **Java Version**: 17+

// returns the number of elements copied, which will be the minimum of
// len(src) and len(dst).
func copy(dst, src []Type) int

// The delete built-in function deletes the element with the specified key
// (m[key]) from the map. If m is nil or there is no such element, delete
// is a no-op.
func delete(m map[Type]Type1, key Type)

// The len built-in function returns the length of v, according to its type:

 * <p>When an instance of ContentCache is created with a byte array, the content is cached in memory.
 * When an instance is created with a File object, the content is cached in the specified file.
 *
 * <p>The {@code close()} method deletes the file if the content is cached in a file.
 *
 * <p>The {@code getInputStream()} method provides an InputStream to read the cached content.
