Set Max Number of Connections to the maximum number of simultaneous client requests that
the server can handle. For each connection, a child httpd process is created. After this maximum
number of processes is reached, no one else can connect to the Web server until a child server
process is freed. You can not set this value to higher than 256 without recompiling. This option
corresponds to the
MaxClients
Connection Timeout defines, in seconds, the amount of time that your server waits for receipts and
transmissions during communications. Specifically, Connection Timeout defines how long your
server waits to receive a GET request, how long it waits to receive TCP packets on a POST or PUT
request, and how long it waits between ACKs responding to TCP packets. By default, Connection
Timeout is set to 300 seconds, which is appropriate for most situations. This option corresponds to

the directive.
TimeOut
Set the Max requests per connection to the maximum number of requests allowed per persistent
