### Choosing between application and network interceptors

Each interceptor chain has relative merits.

**Application interceptors**

 *  New: `ConnectionPool.setPolicy()` configures a minimum connection pool size for a target
    address. Use this to proactively open HTTP connections.

    Connections opened to fulfill this policy are subject to the connection pool's
    `keepAliveDuration` but do not count against the pool-wide `maxIdleConnections` limit.

    a malformed URL.)

 *  **We've improved connect failure recovery.** We now differentiate between
    setup, connecting, and connected and implement appropriate recovery rules
    for each. This changes `Address` to no longer use `ConnectionSpec`. (This is
    an incompatible API change).

 *  **`FormEncodingBuilder` now uses `%20` instead of `+` for encoded spaces.**

   *
   * When a URL is requested, it may be in the context of another URL.
   *
   *  * **Embedded resources like images and iframes** in browsers use the context as the page in
   *    the address bar and the subject is the URL of an embedded resource.
   *
   *  * **Potentially-destructive navigations such as HTTP POST calls** use the context as the page
