+"""
+This inline script modifies a streamed response.
+If you do not need streaming, see the modify_response_body example.
+Be aware that content replacement isn't trivial:
+    - If the transfer encoding isn't chunked, you cannot simply change the content length.
+    - If you want to replace all occurences of "foobar", make sure to catch the cases
+      where one chunk ends with [...]foo" and the next starts with "bar[...].
