Can't create file in CGI Script
Hi I have some simple script within the context of a cgi script that create a file to write to. If I run the script from the command line as root the file is created with no issue. However when I run the script from a web page with the apache account, it dies. The code lines are:

Code:
sub Populate_Session_File       {
        open (NEWOUT,">/var/www/cgi-bin/sessions/$SID") || die "can't open the sessions file";
                print NEWOUT "$SID\011$empnum\011$first_name\011$last_name\011$mailadder\n";
        close (NEWOUT) || die "can't close the spaceout file";
} # end populate session File

And the error I get is:

"[Tue Mar 12 06:07:58 2013] [error] [client IP] can't open the sessions file at /var/www/cgi-bin/riskpect_dsp_login.pl line 238., referer: http://blah.blah
[Tue Mar 12 06:07:58 2013] [error] [client IP] Premature end of script headers: riskpect_dsp_login.pl, referer: http://blah.blah
"

Thanks in advance for any help

bb-snapshot.cgi

BB-SNAPSHOT.CGI(1)					      General Commands Manual						BB-SNAPSHOT.CGI(1)

NAME

       bb-snapshot.cgi - CGI program to rebuild the Xymon webpages for a specific point in time.

SYNOPSIS

       bb-snapshot.cgi

DESCRIPTION

       bb-snapshot.cgi	is  invoked as a CGI script via the bb-snapshot.sh CGI wrapper.  It rebuilds the Xymon web pages to the look they had at a
       particular point in time, based upon the historical information logged about events.

       bb-snapshot.cgi is passed a QUERY_STRING environment variable with the following parameters:

	  mon (Start month of the snapshot)
	  day (Start day-of-month of the snapshot)
	  yr  (Start year of the snapshot)
	  hour (Start hour of the snapshot)
	  min  (Start minute of the snapshot)
	  sec  (Start second of the snapshot)

       The "month" parameters must be specified as the three-letter english month name abbreviation: Jan, Feb, Mar ...

       "day" must be in the range 1..31; "yr" must be specified including century (e.g. "2003"). "hour" must be specified using a 24-hour clock.

       All of the processing involved in generating the report is done by invoking bbgen(1) with the proper "--snapshot" option.

OPTIONS

       --env=FILENAME
	      Load environment from FILENAME before executing the CGI.

       bbgen-options
	      All options except "--env" are passed on to the bbgen(1) program building the snapshot files.

ENVIRONMENT VARIABLES

       BBGENSNAPOPTS
	      bbgen options passed by default to the bb-snapshot.cgi script.  This happens in the bb-snapshot.sh CGI wrapper script.

       BBHOME Home directory of the Xymon server files

       BBSNAP Directory where generated snapshots are stored. This directory must be writable by the userid executing the  CGI	script,  typically
	      "www", "apache" or "nobody". Default: $BBHOME/www/snap/

       BBSNAPURL
	      The URL prefix to use when accessing the reports via a browser.  Default: $BBWEB/snap
