ListenBackLog 3000, Default: ListenBacklog 511 
Sets the maximum length of the queue for pending connections from 511 to 3000.

HotBackup off, Default: HotBackup on 
HotBackup is used to specify whether or not a hot backup server should be started at the server startup time. With the hot backup server active, if the primary server job abnormally terminates, the hot backup will immediately take over and act as the primary and continue servicing requests.  This was set to "off".

TimeOut 320, Default: TimeOut 300
The TimeOut directive currently defines the amount of time the HTTP Server will wait for:
- the amount of time between receipt of TCP packets on a request. 
- the amount of time between ACKs on transmissions of TCP packets in responses.
We set this to 320 seconds. 
 
KeepAliveTimeout 320 , Default: KeepAliveTimeout 300
This determines the number of seconds the HTTP Server waits for a subsequent request before closing the connection.  We set this to 320 seconds versus the default of 300 seconds.
 
ThreadsPerChild 360, Default: ThreadsPerChild 40 
This directive is used to specify the maximum number of threads per server child process. If you do not specify a value for the directive, it inherits the global HTTP Server setting and uses the maximumn listed value.  

LiveLocalCache off , Default: LiveLocalCache on 
The LiveLocalCache directive is used to specify if the cache is updated when a cached file is modified. Set this directive to "on" if you want users, requesting a cached file, to receive the file with the latest updates. Setting this directive to "off" is the optimum setting for performance. 

ServerRoot /QIBM/UserData/HTTPA , Default: none 
The ServerRoot directive sets the directory in which the server lives. Typically it will contain the subdirectories conf/ and logs/. Relative paths for other configuration files are taken as relative to this directory. 

ServerName Firefly.rchland.ibm.com , Default: none 
The ServerName directive sets the hostname of the server.  This is used when creating redirection URLs. If it is not specified, then the server attempts to deduce it from its own IP address.

ScriptAlias /specweb99/ /QSYS.LIB/specweb99.LIB/ , Default: none 
The ScriptAlias directive has the same behavior as the Alias directive, except that in addition it marks the target directory as containing CGI scripts, and then executes the CGI program.  

DocumentRoot / , Default: DocumentRoot /QIBM/UserData/HTTPA/htdocs 
The DocumentRoot directive sets the directory from which the HTTP Server will serve files. If the URL is not matched by a directive like Alias, the server appends the path from the requested URL to the document root and makes the path to the document. 

LogFormat "%h %t \"%r\" %s %b" "Specweb Required" , Default: LogFormat "%h %l %u %t \"%r\" %s %b" 
The LogFormat directive sets the format of the log file. 
 
"CustomLog logs/specweb_access_ssl.log "Specweb required", Default: none 
The CustomLog directive is used to define a log file and the format for each entry in the log file. 

LoadModule sw99_module /QSYS.LIB/SSALPHA8.LIB/MODSW99SSL.SRVPGM , Default: none 
The LoadModule directive links in the object file filename and adds the module structure named module to the list of active modules. 
 
UseShutdown on , Default: off 
This directive instructs the server to use shutdown on the socket connections.
