It's been mentioned previously that resource-constrained implementations may set the table size to 0 (i.e. SETTINGS_HEADER_TABLE_SIZE).

Assume a server has table size 0... Questions:

1. The client's first request will likely include entries that are "Literal Header Field with Incremental Indexing".  I assume it is OK for the server to process a request with this type of literal even though the server won't be adding to its 0-size table?  Am I missing something?

2. If the client is sending multiple requests right after the connection is opened, each request after the first will likely include entries that reference the table (i.e. "Indexed Header Field Representation").  What is an endpoint supposed to do if the peer references something not in its table?  REFUSED_STREAM?  What mechanism should be used to tell the peer to retry?
