Maybe I don't understand what you're asking, or what your server set-up
is... but if you're running curl on another machine, sending a request to
this mysterious server... and your server is then sending more info than
was expected back to the machine that's running curl... it's not curl that's
"pulling info", but instead your machine that's sending it.
Maybe you need to show us verbose output from the instance of curl
that is asking for info, and what it gets back, and also whatever your
server logs show for that process. You might want to xxx-out anything
in that that's too confidential... but it would help if we knew what part
of that info is what you think shouldn't be being sent to curl.
Maybe then someone familiar with server set-up can say if it's possible
to suppress that info from what a server is sending. I think otherwise
your question is too vague.
