[Bug 62654] New: require ssl does not work for h2 protocol

https://bz.apache.org/bugzilla/show_bug.cgi?id=62654

            Bug ID: 62654
           Summary: require ssl does not work for h2 protocol
           Product: Apache httpd-2
           Version: 2.4.34
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: mod_http2
          Assignee: bugs@httpd.apache.org
          Reporter: apache@pessoft.com
  Target Milestone: ---

Hi,

When "Require ssl" directive is used on a resource and resource is accessed
using HTTP/2 protocol over SSL channel, the client is denied the access. When
"SSLRequireSSL" directive is used in such configuration instead "Require ssl",
the client can access the resource. "Require ssl" should not restrict the
access to the resource when HTTP/2 over SSL is used.

For example configuration with mod_ssl and mod_http2:

Protocols h2
<Directory /var/www/html/require>
  require ssl
</Directory>
<Directory /var/www/html/sslrequire>
  sslrequiressl
</Directory>

When client opens https://server.example.org/require/index.html

Found the time to check this. You are correct. mod_ssl did, in this case, not
check correctly on HTTP/2 connections. I fixes this in r1846111 and will
propose this for backport to 2.4.x.
