FTP is your friend. Well, SFTP/FTPS anyway. If you can't tighten the screw with a hammer, maybe try a screwdriver.

RFC 5789 states:







"The PATCH method requests that a set of changes described in the request entity be applied to the resource identified by the Request-URI. The set of changes is represented in a format called a 'patch document' identified by a media type."



Suggest brushing up on "media type". You're modifying a resource, not a type of content. A text/html representation of a CSV diagnostic file may be generated for rendering in a browser. Probably best to patch the resource by sending a snippet of CSV, as patching the HTML *representation* may inadvertently break the CSS. Not to mention needs reverse-transformed before applying to the resource.



You just need a "patch document" with a media type defining it as CSV, maybe even with line numbers.
