Bug ID: 59313
Summary: module mod_http2 - incorrect protocol version string.
Product: Apache httpd-2
Version: 2.4.18
Hardware: All
OS: All
Status: NEW
Severity: trivial
Priority: P2
Component: mod_http2
Assignee: [email protected]
Reporter: [email protected]
RFC 3875 defines the HTTP version number as "<major>.<minor>" for the purposes
of the CGI variable "SERVER_PROTOCOL". This implementation simply has
"HTTP/2", which has no minor number.
Change line 408 of file modules/http2/h2_request.c to read "HTTP/2.0".
ap_parse_uri(r, req->path);
- r->protocol = (char*)"HTTP/2";
+ r->protocol = (char*)"HTTP/2.0";
r->proto_num = HTTP_VERSION(2, 0);
RFC 7540 did NOT override RFC 3875 but claims backward compatibility. Granted
that RFC 7540 refers to the second, binary implementation of HTTP as "HTTP/2",
that was insufficient to override the ABNF syntax for the CGI interface in the
absence of an affirmation of such an override.
RFC 3875, Section 4.1.16 ABNF:
HTTP-Version = "HTTP" "/" 1*digit "." 1*digit
The "minor" number is not optional.
