Subject Re: flowfile through invokehttp put

Normally this would all be handled for you with site-to-site, but not
sure that can be made to work with your custom proxy. Before
site-to-site there was PostHttp and ListenHttp, and PostHttp has an
options for "Send As Flow File". PostHTTP is marked as deprecated
because generally you should use site-to-site or InvokeHttp, but
InvokeHttp doesn't have the send as flow file concept. So you could
try using PostHttp as long as you realize its deprecated, and maybe
someone can add the send as flow file concept to InvokeHttp, or maybe
a PackageContent processor.

The only other option I can think of is to use MergeContent with the
Merge Format set to "FlowFile Stream v3" and configure the max and min
entries to 1 so it doesn't really actually merge anything, but just
writes out the new flow content. On the receiving side use
UnpackContent also configured with format as "FlowFile Stream v3".
