+`Session`'s state also includes any custom headers and content being sent. Once you performed a request both will be re-attached to any subsequent request. Resending the body can be prevented by a call to `RemoveContent()`, while headers can also be deleted manually:

+cpr::Session session;
+session.SetUrl(postUrl);

+session.SetBody(Body{"x=5"});
+
+cpr::Response postResponse = session.Post();
+std::cout << postResponse.text << std::endl;
+// [...] "headers": " My-Custom-Header": " hello", "Content-Type": "application/json" [...] "data": "x=5"
+
+session.RemoveContent();                    // don't send a body in next request

 `Session` also allows you to get the full request URL before a request is actually made:
