+    BUG/MINOR: channel: inject output data at the end of output
+    
+    In co_inject(), data must be inserted at the end of output, not the end of
+    input. For the record, this function does not take care of input data which are
+    supposed to not exist. But the caller may reset input data after or before the
+    call. It is its own choice.
+    
+    This bug, among other effects, is visible when a redirect is performed on
+    the response path, on legacy HTTP mode (so for HAProxy < 2.1). The redirect
+    response is appended after the server response when it should overwrite it.
+    
+    Thanks to Kevin Zhu <ip0tcp@gmail.com> to report the bug. It must be backported
+    as far as 1.9.
+
