* QUIC Test Server Module
|
|
* =======================
|
|
*
|
|
* This implements a QUIC test server. Since full QUIC server support is not yet
|
|
* implemented this server is limited in features and scope. It exists to
|
|
* provide a target for our QUIC client to talk to for testing purposes.
|
|
*
|
|
* A given QUIC test server instance supports only one client at a time.
|
|
*
|
|
* Note that this test server is not suitable for production use because it does
|
|
* not implement address verification, anti-amplification or retry logic.
