| 6 | * CaseInsensitiveArray is an array-like class that ignores case for keys. |
| 7 | * |
| 8 | * It is used to store HTTP headers. Per RFC 2616, section 4.2: |
| 9 | * Each header field consists of a name followed by a colon (":") and the field value. Field names |
| 10 | * are case-insensitive. |
| 11 | * |
| 12 | * In the context of stripe-php, this is useful because the API will return headers with different |
| 13 | * case depending on whether HTTP/2 is used or not (with HTTP/2, headers are always in lowercase). |
