### Motivation

This library makes it easy to test that your app Does The Right Thing when it
makes HTTP and HTTPS calls. It lets you specify which responses to return and
then verify that requests were made as expected.

Because it exercises your full HTTP stack, you can be confident that you're
testing everything. You can even copy & paste HTTP responses from your real web

    var b = 0
    for (codePoint in input) {
      if (codePoint < INITIAL_N) {
        result.writeByte(codePoint)
        b++
      }
    }

    // Copy a delimiter if any basic code points were emitted.
    if (b > 0) result.writeByte('-'.code)

    var n = INITIAL_N
    var delta = 0
    var bias = INITIAL_BIAS
    var h = b
    while (h < input.size) {

 * Fix: Support SPDY header blocks with trailing bytes.
 * Fix: Allow `;` as separator for `Cache-Control` header.
 * Fix: Correct bug where HTTPS POST requests were always automatically buffered.
 * Fix: Honor read timeout when parsing SPDY headers.

We are thankful for their work.

We can see that we were redirected because `response.request().url()` is different from `request.url()`. The two log statements log two different URLs.
