This is amazing idea! Is there any potential harm to implement 403 on MRS right now, without support from major server and client apps support? |
| For the federation endpoint specifically, the local user SHOULD have the remote server's error proxied | ||
| straight through to them, however some implementations may prefer to replace the error before serving | ||
| it to their users. This can help reduce the potential of remote Cross-Server Scripting (XSS) attacks. |

Is there any guidance on when a server may wish to replace it?
| Specific error codes are a potential alternative, however due to the wide variety of illegal material | ||
| and jurisdictions, this proposal has determined that a single, generic, error code with specific message | ||
| more easily covers the use cases. |

This made me think that it was at least adding an error message for illegal content, but I see it is a generic "FORBIDDEN" -- I guess the rationale is that this can be applied for many different cases.

@clokep, implementations like invent.kde.org/network/neochat/-/merge_requests/2023#note_1079171 at least use specific error messages.

I meant "error code", not "error message" sorry for the confusion.
See matrix-org/matrix-spec-proposals#4228 for details. Since this is tricky to test without server-side support, I have added a basic implementation to the mock server in appiumtests/login-server.py 1. Start appiumtests/login-server.py 2. Start neochat with "--test --ignore-ssl-errors" options 3. Open "Explore Rooms" 4. Search for the exact string "forbidden" 5. See new error message provided by server

I have implemented the client side of this MSC in NeoChat: https://invent.kde.org/network/neochat/-/merge_requests/2023 - For now without support for MSC4176
