Add HTTP server timeouts to index-server and chunk-server#329
Conversation
Set ReadHeaderTimeout (30s) and IdleTimeout (120s) on the http.Server used by both index-server and chunk-server. Without these, an Internet- exposed server is vulnerable to Slowloris-style header-read attacks and unbounded idle keep-alive connections. ReadTimeout and WriteTimeout are intentionally left at 0 so that slow but legitimate transfers of large chunks or indexes aren't cut off.
