Hi list,
I'm having a problem with my perl scripts after I ported them into a new
server environment.
My server environment:
Apache2 2.0.55
Perl 5.8.3
CGI 3.15
mod_perl 2.0.2
What is happening is that _occasionaly_ (maybe 1 out of 20 times) the POST
data users send by their browser to my perl scripts is not arriving. Instead
my parameters stay empty. When I look into the environment variables I can
see that the CONTENT_LENGTH returns the right value for the data ought to
arrive. For the errorprone calls I also used CGI::Batch to look into the
POST data and still it was empty. It is very hard to reproduce the error
intentionally - e.g. when I refresh a POST call to my perl script 50 times
it happens that the 51st time the data is gone and the 52nd time everything
is fine again.
The used code looks like this:
print "Content-type:text/html\n\n";
use CGI qw/:standard/;
use CGI::Carp 'fatalsToBrowser';
my $query = new CGI;
my $name = $query->param('name');
my $pass = $query->param('pass');
The environment variables of an exemplary call returning empty post data
like this:
SCRIPT_NAME=...
SERVER_NAME=...
HTTP_REFERER=...
SERVER_ADMIN=...
HTTP_ACCEPT_ENCODING=gzip, deflate
HTTP_CONNECTION=Keep-Alive
REQUEST_METHOD=POST
CONTENT_LENGTH=35
HTTP_ACCEPT=image/gif, image/x-xbitmap, image/jpeg, image/pjpeg,
application/x-shockwave-flash, application/msword,
application/vnd.ms-powerpoi nt, application/vnd.ms-excel, */*
SCRIPT_FILENAME=...
SERVER_SOFTWARE=Apache/2.0.55 (Unix) mod_perl/2.0.2 Perl/v5.8.3
QUERY_STRING= REMOTE_PORT=61160 HTTP_USER_AGENT=Mozilla/4.0 (compatible;
MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322) SERVER_PORT=80
SERVER_SIGNATURE=<address>Apache/2.0.55 (Unix) mod_perl/2.0.2 Perl/v5.8.3
Server at ...</address>
HTTP_CACHE_CONTROL=no-cache
HTTP_ACCEPT_LANGUAGE=de
HTTP_COOKIE=...
REMOTE_ADDR=217.85.246.87
CONTENT_TYPE=application/x-www-form-urlencoded
SERVER_PROTOCOL=HTTP/1.1
PATH=/usr/sbin:/bin:/usr/bin:/sbin:/usr/X11R6/bin
REQUEST_URI=...
GATEWAY_INTERFACE=CGI/1.1
SERVER_ADDR=...
DOCUMENT_ROOT=...
HTTP_HOST=...
I should mention that the same scripts performed without any errors in my
earlier server environment which I unfortunately cannot reference to with
exact version numbers - for sure I know only that it was an Apache 1.3 withd
mod_perl < 2 ...
Any feedback is appreciated,
Thomas
