Resolved Connection keep-alive

[DieterWerner]

I added

<ifModule mod_headers.c>
Header set Connection keep-alive
</ifModule>

into the Vhost.conf but it took no effect.

So what should I do?

I use Centos 7.

Hi DieterWerner,

pls. consider to provide MORE informations:

Do you use a combination of nginx and apache?
It would help to investigate as well your domain - specific log - files and the serverwide apache ( and nginx? ) - logs.

=> Plesk for Linux services logs and configuration files ( KB - article: 213403509 )​

 

[DieterWerner]

Yes - I use the combination of nginx and apache and I checked the log files you mentioned.

Hi DieterWerner,

IF you use nginx+apache, you should be aware, that apache is able to read ".htaccess" - files, but nginx can't do that.

To inform yourself, how you are able to setup nginx, pls. read the official NGINX documentation:

=> Module ngx_http_core_module
=> Module ngx_http_core_module
=> Module ngx_http_core_module

For further informations, pls. read for example: => Enable Keep-Alive to speed up your website​

My question doesn't concern the content of .htaccess
I would like to enable KeepAlive via httpd.conf or vhost.conf

Hi DieterWerner,

I would like to enable KeepAlive via httpd.conf or vhost.conf

... which brings us back to your answer:

Yes - I use the combination of nginx and apache

... where NGINX is in front of your apache webserver and you should therefore consider to add the corresponding settings there as well.

 

[DieterWerner]

As long as KeepAlive On ist not a part of the httpd.confi - it's useless to add the settings into the ngingx config.

Hi DieterWerner,

it's useless to add the settings into the ngingx config

... if you think this way, could you pls. check, WHO answers your first request, when you connect to your webserver? Is it NGINX, or is it Apache?

Example URL to check your header: => HTTP Header Check | HackerTarget.com​

If I'm not mistaken, simply adding the header to "keep-alive" won't do anything unless the server has the capability turned on in the settings file.
(ie, for Apache the setting is "KeepAlive on" in the server settings)
