old days of the web, the HTTP protocol was simple but not efficient:
|

one connection was made for each objects requested by a client. That
|
|
means a web browser made 20 connections to the webserver if there was
|
|
19 images on a webpage and the HTML page itself. This result in
|
|
a lot of overhead and response time delay. With keep alive, the server
|
|
don't close the connection for each objects so the browser can request
|
|
several objects with one HTTP connection and does not need to
|
|
reconnect each time. As a result, the website seems to be faster for
|
|
the client and the webserver can handle more users.

This is a very useful option. For example you can start several Caudium instances
|
|
with different configurations by using different configuration
|
|
directories. This is also useful if you put the configuration files in a non-standard
|
|
directory:
|
|
<TT
|
|
CLASS="computeroutput"
|
|
> /usr/local/caudium/server/start --config-dir=/home/david/etc/my_caudium_configuration/
|
|
</TT
|
|
>
|
|
For Apache users, this is the equivalent of the <TT
|
|
CLASS="option"
|
|
>-f</TT
|
|
> option but points to
|
|
the directory that contains the files.

CLASS="filename"
