DACS_PRENV(8)						     DACS Web Services Manual						     DACS_PRENV(8)

NAME

       dacs_prenv - CGI program that displays its environment

SYNOPSIS

       dacs_prenv [-html]

DESCRIPTION

       This program is part of the DACS suite. It is a stand-alone program that neither accepts the usual DACS command line options (dacsoptions)
       nor accesses any DACS configuration files.

       This CGI utility simply prints its command line arguments, all environment variables, information about the system on which it is running,
       and CGI parameters and their values. It can be a useful tool when debugging web services.

	   Tip
	   This program can be a useful tool for debugging web services. Replace a call to your web service with an identical call to dacs_prenv
	   to see what arguments your web service is being passed and (to some extent) other context.

OPTIONS

       dacs_prenv recognizes these command line flags:

       -html
	   Selects HTML output (text/html) instead of the default Content-Type of text/plain, by default, using the style sheet dacs_prenv.css[1].

   Web Service Arguments
       When used as a web service, the following parameters are recognized:

       FORMAT
	   At present, the only recognized value for this argument is HTML.

       just_dump_stdin
	   If the value of QUERY_STRING is exactly jump_dump_stdin, then the program will simply copy its standard input to the standard output as
	   text/plain.

FILES

       dacs_prenv.css[1]

DIAGNOSTICS

       The program exits 0 if everything was fine, 1 if an error occurred.

BUGS

       It should be possible to request XML output.
