Synapse: consider proxying/302ing large remote media files

[richvdh]

if Bob uploads a huge file to his HS, and Alice tries to fetch it, but it's too large for her homeserver, she'll just get an error ({errcode:M_TOO_LARGE,error:Requested file is too large > 104857600 bytes}). Could Alice's HS instead just proxy the request and stream the file from Bob's HS?

Wouldn't it also be possible to 302 to the origin server?

mmm. good point.

From a privacy perspective I would prefer proxying. Else I could send a x GB file to a room just to observe the IP Addresses of the users.
