| * h2_from_h1 parses a HTTP/1.1 response into |
| * - response status |
| * - a list of header values |
| * - a series of bytes that represent the response body alone, without |
| * any meta data, such as inserted by chunked transfer encoding. |
| * |
| * All data is allocated from the stream memory pool. |
| * |
| * Again, see comments in h2_request: ideally we would take the headers |
| * and status from the httpd structures instead of parsing them here, but |
| * we need to have all handlers and filters involved in request/response |
| * processing, so this seems to be the way for now. |
