Bug ID: 56935
Summary: TIMEOUT used instead of KeepAliveTimeout when header
"connection : keep-alive" is not used
Product: Apache httpd-2
Version: 2.4.4
Hardware: PC
OS: Windows XP
Status: NEW
Severity: normal
Priority: P2
Component: Core
Assignee: [email protected]
Reporter: [email protected]
I use a special client (a proxy may have such behavior also) that handles
HTTP/1.1 persistent connection. I use the default configuration on Apache 2.4.4
It does not use the dedicated header "connection : keep-alive". As a
consequence, by default the persistent connection is used. My client also keeps
the TCP connection alive by using TCP keep-alive. I notice that the server
never closes the TCP connection after 5s of HTTP inactivity (KeepAliveTimeout).
I have to wait the 300s timeout (key TIMEOUT).
According to the Apache documentations it seems that this connection should
have close after no KeepAliveTimeout of HTTP Activity. I believe that the
server considers the TCP Keepalive packet as HTTP message and then waits
TIMEOUT instead. Thus it gives an easy scheme to consume Apache resources.
For information my TCP keepalive are quite basic : only One byte of data set to
0.
