Hi all,
I have a weird problem using a script in a CGI environment together with
Mozilla Firefox (1.0.3) that, to me, makes no sense at all, but I hope it
does to you.
Here's what happened to me.
I have a neatly running database-oriented application in Perl based on a
script that acts as a developing tool and is being used intensively for 6
years now on our intranet and internet sites. The application works fine in
MSIE6 and Opera7.11, but in Firefox1.0.3, the browser does not show the
contents in the main screen but starts the download-or-open dialog ('You
have chosen to open query.pl which is a: PL file, from www2.minlnv.nl. What
should Firefox do with this file: Open with / Save to disk'). When I choose
'Save to disk' the saved file is the exact HTML that should have been opened
in the browser. So, all code is executed fine.
Sounds like an incorrect http header to me. The script starts with some
'use'-commands, then
print "Content-Type: text/html\n\n";
then a few subroutines, then the main program.
When I change my script as follows:
print "Content-Type: text/html\n\n";
print 'x';
exit;
followed by my original code, same behaviour (including just an 'x' in the
downloaded file)
Now for the weird part of it.
When I change my script as follows:
print "Content-Type: text/html\n\n";
print 'x';
exit;
*and delete* the rest of the code, the browser shows 'x' instead of the
dialog.
Note that this was code that compiles and executes without problems. It
makes a difference *after* the exit statement. The remaining code has no
END routines so I expect exit does not more than exit. Changing exit to
exit(0) or exit(1) makes no difference.
BTW. When I replace the self-contructed header with
$cgiobj = new CGI;
print $cgiobj->header;
the same behaviour.
And then, finally, when I try the following script:
use LWP::Simple;
print "Content-Type: text/html\n\n";
$doc = get
'http://www2.minlnv.nl/cgi-bin/database/query.pl?config=/thema/groen/ffwet/s
oorten&snp=zoeken-public';
print $doc;
I *do* get my content in the browser window, which indicates that the sent
HTML is not the cause.
Who can help?
Thanks in advance,

Program code: available from http://www.agro.nl/tmp/query.zip - you'll get a
nice impression of my programming style of 6 years ago :-) but I can't
possibly ask you to take a dive into the code details.
