[jira] [Commented] (TS-3847) Rejects Dynamic Table Size if it does not appear at the beginning of the first header block

["Masakazu Kitajo (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TS-3847?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14969318#comment-14969318 ] 

Masakazu Kitajo commented on TS-3847:
-------------------------------------

I think the point is the order, but not the number of dynamic table size update.

In the h2spec test,
The header block contains some header fields and two dynamic table size updates. This is valid.
The updates appear AFTER the header fields. This is not valid.

"This dynamic table size update MUST occur *at the beginning of the first header block* following the change to the dynamic table size. In HTTP/2, this follows a settings acknowledgment (see Section 6.5.3 of \[HTTP2\])."
