 *  Fix: don't return stale DNS entries in `DnsOverHttps`. We were caching DNS results indefinitely
    rather than the duration specified in the response's cache-control header.

    containing an IP address we must match that address against the URL's IP address, even when the

 * Pinning is per-hostname and/or per-wildcard pattern. To pin both `publicobject.com` and

 *
 *  * **Full domain name**: you may pin an exact domain name like `www.publicobject.com`. It won't
 *    match additional prefixes (`us-west.www.publicobject.com`) or suffixes (`publicobject.com`).

### Posting form parameters ([.kt][PostFormKotlin], [.java][PostFormJava])

Use `FormBody.Builder` to build a request body that works like an HTML `<form>` tag. Names and values will be encoded using an HTML-compatible form URL encoding.
