svn commit: r1899649 - in /httpd/httpd/trunk: ./ modules/http2/ test/modules/http2/
Author: icing
Date: Thu Apr 7 10:55:09 2022
New Revision: 1899649
URL: http://svn.apache.org/viewvc?rev=1899649&view=rev
Log:
*) mod_http2: use the new RESPONSE buckets introduced in r1899648.
This replaces the internal H2_HEADERS bucket, removing its
source file and also obsoletes any interim response parsing
needs.
