DESCRIPTION

dta-cab-http-server.perl is a command-line utility for starting a standalone HTTP server to perform DTA::CAB token-, sentence-, and/or document-analysis using the DTA::CAB::Server::HTTP module.

See dta-cab-http-client.perl(1) for a command-line client using the DTA::CAB::Client::HTTP module.

OPTIONS AND ARGUMENTS

General Options

-help

Display a short help message and exit.

-man

Display a longer help message and exit.

-version

Display program and module version information and exit.

-verbose LEVEL

Alias for "-log-level LEVEL".

Server Configuration Options

-config PLFILE

Load server configuration from PLFILE, which should be a perl source file parseable by DTA::CAB::Persistent::loadFile() as a DTA::CAB::Server::HTTP object.

-bind HOST

Override host on which to bind server socket. Default is to bind on all interfaces of the current host.

-port PORT

Override port number to which to bind the server socket. Default is whatever DTA::CAB::Server::HTTP defaults to (usually 8088).

Daemon Mode Options

-daemon , -nodaemon

Do/don't fork() a server subprocess (default: don't). If running in daemon mode, the program should simply spawn a single server subprocess and exit, reporting the PID of the child process.

Useful for starting persistent servers from system-wide init scripts. See also "-pidfile FILE".

-pidfile FILE

Writes PID of the server process to FILE before running the server. Useful for system init scripts.

Logging Options

The DTA::CAB family of modules uses the Log::Log4perl logging mechanism. See Log::Log4perl(3pm) for details on the general logging mechanism.

-log-level LEVEL

Set minimum log level. Has no effect if you also specify "-log-config". Known levels: (trace|debug|info|warn|error|fatal).

-log-config L4PFILE

User log4perl config file L4PFILE. Default behavior uses the log configuration string returned by DTA::CAB::Logger->defaultLogConf().

-log-watch , -nowatch

Do/don't watch log4perl config file (default=don't). Only sensible if you also specify "-log-config".
