<p>The Access-Control-Allow-Headers response header is used in response to
|
||
a preflight request to indicate which HTTP headers will be available via
|
||
Access-Control-Expose-Headers when making the actual request.</p>
|
||
<p>The simple headers, Accept, Accept-Language, Content-Language,
|
||
Content-Type (but only with a MIME type of its parsed value (ignoring
|
||
parameters) of either application/x-www-form-urlencoded,
|
||
multipart/form-data, or text/plain), are always available and don’t need
|
||
to be listed by this header.</p>
|

<p>This header is required if the request has an
|
||
Access-Control-Request-Headers header.</p>
