> Hi all,
> I implemented method 'readEntityMedia' which is called via $value for an entity. As I do return a PDF file I like to set the response header 'Cache-Control' to a defined value which is 'max-age = 86400, public' in my case.
> By default the 'Cache-Control' header is set to private. I tried to change the header by using method 'header' of the ODataResponseBuilder:
> {code:borderStyle=solid}
> public ODataResponse readEntityMedia(GetMediaResourceUriInfo uriInfo, String contentType) throws ODataException {
> ...
> ODataResponseBuilder responseBuilder = ODataResponse.fromResponse(EntityProvider.writeBinary(mimeTypeRequested, documentData));
> 				
> responseBuilder
> 	.header("Cache-Control", "max-age = 86400, public")
> 	.header("Content-Disposition", "inline;filename=\"" + fileName + "\"");
> 				
> return responseBuilder.build();
> }
> {code}
> Unfortunately the response header now contains both:
> Cache-Control:private 
> and
> Cache-Control:max-age = 86400, public
> which is not what I expected. By calling method 'header' of the ResponseBuilder I expect that if a header already exists it gets overwritten.
> Best regards,
> Alex
