Bug ID: 65844
Summary: Expect: 100-continue changed behavior in ecebcc0
Product: Apache httpd-2
Version: 2.4.49
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P2
Component: Core
Assignee: bugs@httpd.apache.org
Reporter: pgaj...@suse.cz
Target Milestone: ---
https://github.com/apache/httpd/commit/ecebcc035ccd8d0e2984fe41420d9e944f456b3c
seem to had changed behavior for 'Expect: 100-continue'. For
https://github.com/pgajdos/apache-rex/tree/master/mod_ssl-proxy-auth
I get with 2.4.48+ecebcc0:
[1] with Expect: 100-continue
* SSL connection using TLSv1.2 / ECDHE-RSA-AES256-GCM-SHA384
< Connection: close
* Closing connection 0
* SSL connection using TLSv1.2 / ECDHE-RSA-AES256-GCM-SHA384
* Connection #1 to host frontend.su.se left intact
[2] without Expect: 100-continue
* SSL connection using TLSv1.2 / ECDHE-RSA-AES256-GCM-SHA384
* Connection #0 to host frontend.su.se left intact
* Re-using existing connection! (#0) with host frontend.su.se
* Connection #0 to host frontend.su.se left intact
For 2.4.48 I get in [1] the same behavior (reusing connection) as in
[2] here. Is that intended? If I got it correctly, some site have a
problem with not maintaining keepalive connection after 401.
