man dacs_prenv (8): 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 m[blue]dacs_prenv.cssm[][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.
