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.
