### Set object lock

PutObject API allows setting per object retention mode and retention duration using `x-amz-object-lock-mode` and `x-amz-object-lock-retain-until-date` headers. This takes precedence over any bucket object lock configuration w.r.t retention.

```sh

 * Fix: Drop `Content-Length` header when redirected from POST to GET.
 * Fix: Correctly read cached header entries with malformed header names.
 * Fix: Do not directly support any authentication schemes other than "Basic".
 * Fix: Respect read timeouts on recycled connections.
 * Fix: Transmit multiple cookie values as a single header with delimiter.

* `path` - The file path to the file to stream.
* `headers` - Any custom headers to include, as a dictionary.
* `media_type` - A string giving the media type. If unset, the filename or path will be used to infer a media type.
* `filename` - If set, this will be included in the response `Content-Disposition`.

File responses will include appropriate `Content-Length`, `Last-Modified` and `ETag` headers.

## Add custom headers { #add-custom-headers }

There are some situations in where it's useful to be able to add custom headers to the HTTP error. For example, for some types of security.

You probably won't need to use it directly in your code.

But in case you needed it for an advanced scenario, you can add custom headers:

     * Imports elevate words from a CSV file.
     * Expected CSV format: SuggestWord, Reading, Permissions, Labels, Boost
     *
     * @param reader the Reader containing CSV data to import
     */
    public void importCsv(final Reader reader) {
        final PermissionHelper permissionHelper = ComponentUtil.getPermissionHelper();
        final CsvConfig cfg = new CsvConfig(',', '"', '"');

			// Make sure we remove any existing headers before
			// proxying the request to another node.
			for k := range w.Header() {
				w.Header().Del(k)
			}
			globalForwarder.ServeHTTP(w, r)
			return
		}
		h.ServeHTTP(w, r)
	})
}

// addCustomHeadersMiddleware adds various HTTP(S) response headers.
// Security Headers enable various security protections behaviors in the client's browser.

      requestBuilder.header("Accept-Encoding", "gzip")

    val cookies = cookieJar.loadForRequest(userRequest.url)
    if (cookies.isNotEmpty()) {
      requestBuilder.header("Cookie", cookieHeader(cookies))
    }

    if (userRequest.header("User-Agent") == null) {
      requestBuilder.header("User-Agent", USER_AGENT)
    }
