> In NMWebService/AHSWebservice, we have used CONTENT-DISPOSITION header for show/download
container logs. Looks like it has security risks. And people have devised content-disposition
hacking.
> The HTTP 1.1 Standard (RFC 2616) also mentions the possible security side effects of
content disposition:
> {code}
> 15.5 Content-Disposition Issues
>    RFC 1806 [35], from which the often implemented Content-Disposition
>    (see section 19.5.1) header in HTTP is derived, has a number of very
>    serious security considerations. Content-Disposition is not part of
>    the HTTP standard, but since it is widely implemented, we are
>    documenting its use and risks for implementors. See RFC 2183 [49]
>    (which updates RFC 1806) for details.
> {code}
