If the previous response was cached it will get reused, resulting in the client tight looping making the same request and never making any progress. In general, clients will expect to get up to date data when requesting APIs, and so its safer to do a blanket no cache policy than only whitelisting APIs that we know will break things if they get cached. --- synapse/http/server.py | 1 + 1 file changed, 1 insertion(+) (limited to 'synapse/http') diff --git a/synapse/http/server.py b/synapse/http/server.py index 1551db239d..f19c068ef6 100644 --- a/synapse/http/server.py +++ b/synapse/http/server.py @@ -488,6 +488,7 @@ def respond_with_json_bytes(request, code, json_bytes, send_cors=False, request.setHeader(b"Content-Type", b"application/json") request.setHeader(b"Server", version_string) request.setHeader(b"Content-Length", b"%d" % (len(json_bytes),)) + request.setHeader(b"Cache-Control", b"no-cache, no-store, must-revalidate") if send_cors: set_cors_headers(request) -- cgit 1.4.1
