[GitHub] [trafficserver] maskit opened a new issue, #9426: H3 header size constraints
maskit opened a new issue, #9426:
URL: https://github.com/apache/trafficserver/issues/9426
Need to support `SETTINGS_MAX_FIELD_SECTION_SIZE`.
https://datatracker.ietf.org/doc/html/rfc9114#name-header-size-constraints
There are similar thing in H2 as well and we have `proxy.config.http2.max_header_list_size` for it.
https://datatracker.ietf.org/doc/html/rfc9113#name-limits-on-field-block-size
Note that the size is not the total of the lengths of field names and values.
> The size of a field list is calculated based on the uncompressed size of fields, including the length of the name and value in bytes plus an overhead of 32 bytes for each field.

Actually, I found `Http3SettingsId::HEADER_TABLE_SIZE`. It seems like the name was changed on the spec at some point. We may just need to rename variables and functions.

Actually I think it's the `Http3SettingsId::MAX_HEADER_LIST_SIZE` that's been renamed.
