SSE forwarding for A2A protocol

[shaffi]

A2A agents deployed on AgentCore with serverProtocol: A2A have their SSE responses buffered by the proxy. The same agent redeployed with serverProtocol: HTTP using BedrockAgentCoreApp streams incrementally. Is there a configuration to enable
incremental SSE forwarding for A2A protocol agents?

I'm not sure about the exact configuration for AgentCore, but you need to ensure that the proxy handling SSE for serverProtocol: A2A doesn't buffer responses. You can typically adjust buffer settings or use a different proxy setup. Here's an example for a typical HTTP proxy configuration:

ProxyPass /your-endpoint http://your-agent-endpoint
ProxyPassReverse /your-endpoint http://your-agent-endpoint

SetEnv proxy-sendchunks 1

This works by disabling response buffering in the proxy setup.
