rmarx commented on this pull request. > @@ -1335,8 +1343,8 @@ The following settings are defined in HTTP/3: : The default value is unlimited. See {{header-formatting}} for usage. SETTINGS_NUM_PLACEHOLDERS (0x9): - : The default value is 0. However, this value SHOULD be set to a non-zero - value by servers. See {{placeholders}} for usage. + : The default value is 0. However, servers SHOULD set this value to 32 or I also suggested 32 because the "power of two" feeling. Otoh, I was thinking about Patrick Meenan's setup, which requires 4 placeholders per priority level in the current scheme, allowing for 8 priority levels if the minimum number of placeholders is 32. 8 is more than e.g., the 5 chrome is using at the moment, but seems like a good number (see also SPDY priority levels). I just want to prevent us setting this to a too low a number (e.g., 10), since that would counteract the purpose of setting a lower bound imo. -- You are receiving this because you are subscribed to this thread.
