 * ### Path
 *
 * The path identifies a specific resource on the host. Paths have a hierarchical structure like
 * "/square/okhttp/issues/1486" and decompose into a list of segments like `["square", "okhttp",
 * "issues", "1486"]`.
 *
 * This class offers methods to compose and decompose paths by segment. It composes each path

    assertThat(url.resolve("").toString()).isEqualTo("http://%25:%25@host/%25?%25")
  }

  /**
   * Although HttpUrl prefers percent-encodings in uppercase, it should preserve the exact structure
   * of the original encoding.
   */
  @Test
  fun rawEncodingRetained() {
    val urlString = "http://%6d%6D:%6d%6D@host/%6d%6D?%6d%6D#%6d%6D"
    val url = parse(urlString)

   * across different segments.
   *
   * The page replacement algorithm's data structures are kept casually consistent with the map. The
   * ordering of writes to a segment is sequentially consistent. An update to the map and recording
   * of reads may not be immediately reflected on the algorithm's data structures. These structures
   * are guarded by a lock and operations are applied in batches to avoid lock contention. The

   * String a1 = peekingIterator.peek(); // returns "a"
   * String a2 = peekingIterator.peek(); // also returns "a"
   * String a3 = peekingIterator.next(); // also returns "a"
   * }
   *
   * <p>Any structural changes to the underlying iteration (aside from those performed by the
   * iterator's own {@link PeekingIterator#remove()} method) will leave the iterator in an undefined
   * state.
