in my httpd.conf there is:
KeepAliveTimeout 1
I'm trying to override Apache KeepAliveTimeout setting in a single php script (not in the entire server) so I have a php script with:
header("Keep-Alive: timeout=60, max=100");
but it doesn't seem to make any difference. still I get in the response:
Keep-Alive:timeout=1, max=50
any ideas how to solve this?
You can't do that. It's there in place for a valid reason.
Apache v2.2 Core Features
The number of seconds Apache will wait for a subsequent request before closing the connection. Once a request has been received, the timeout value specified by the Timeout directive applies.
Setting KeepAliveTimeout to a high value may cause performance problems in heavily loaded servers. The higher the timeout, the more server processes will be kept occupied waiting on connections with idle clients.
Try setting it in the .htaccess file combined with a FilesMatch directive. See this post.
<?php
header('Connection: close');
// other php code here...
// ...
From RFC 2616, Section 14.10:
HTTP/1.1 defines the "close" connection option for the sender to
signal that the connection will be closed after completion of the
response. For example,Connection: closein either the request or the response header fields indicates that the connection SHOULD NOT be considered `persistent' (section 8.1)
after the current request/response is complete.HTTP/1.1 applications that do not support persistent connections MUST include the "close" connection option in every message.
