Upload file to Apache server using Perl/CGI on Windows

[easye42]

Hi,

I keep getting this error when I upload files from the browser to me Apache server: "CGI.pm: Server closed socket during multipart read (client aborted?).". I'm now running Perl 5.8 on Apache on Windows. I'm only reciveing the error when I upload files that are greater than 8k. I don't have a problems with files that are 8k or less but from 9k this errors always occurs and these are all files of the same type. I've tried in Netscape and Internet Explorer and they both do the same thing.

Help would be greatly appreciates.

Thanks

have you got the latest version of CGI ?

Can we see some code?

# Var: $subject
# ================================================================ #
# the subject of the e-mail notification. if you have a field in
# your form named "subject" in lowercase, that will over-ride this

$subject = 'Upload Form Submission';

# ================================================================ #
# Var: $dir
# ================================================================ #
# enter your server's path (not your website address) to the
# directory files will be uploaded to.
# note : this script does not auto-delete uploaded files.
# consider one of our other scripts if auto-deletion is required
#
# on most unix/linux server $ENV{DOCUMENT_ROOT}/ points to the
# folder your homepage resides in. however, sometimes you need to
# also add

http://www or

htdocs to the path
#
# on windows servers, start the path with the drive letter and
# separate each folder with two backslashes.
# e.g. $dir = "F:\\webpath\\

http://wwwroot\\uploads

#
# if you get this wrong, the script will print the correct path

$dir = "e:\\web\\damion\\temp";

http://)

to folder

# Var: $max
# ================================================================ #
# maximum file size (in kilobytes) you will accept as an upload.
# your host can, and often, does override this setting. if you
# cannot upload very large files, contact your host. it's not the
# the script, it's the server. this script has successfully uploaded
# files larger than the Windows XP operating system!
# 1024 kilobytes is equal to 1 megabyte

# $max = 1024;

# ================================================================ #
# Var: $print_contents
# ================================================================ #
# set to 1 if you would like the contents of your upload directory
# ($dir) printed after a successful upload. set to 0 if you do not
# want filenames printed. note: this is ignored if redirecting the
# submitter to another page upon successful submission

$print_contents = 1;

# ================================================================ #
# Var: $overwrite
# ================================================================ #
# if the name of the file being uploaded already exists in your
# upload directory ($dir) and you DO NOT WANT it over-written,
# set this variable to 0 (zero). the script will then automatically
# rename the file by appending a unique number to it.
# if you DO WANT existing files to be over-written by the new upload,
# then set this variable to 1

$overwrite = 0;

# ================================================================ #
# Var: $domain
# ================================================================ #
# to ensure this script only processes forms that reside on your
# website, enter your domain name in this variable. the

http://www

# portion is not required and best not be used.
#
# this helps prevent "hi-jacking" of your form. a technique
# practiced by hackers to have a program on their website or local
# computer programatically send out spam.
#
# note: this security measure is not fool proof and can be easily
# circumvented by hackers. additionally, some web surfers may
# unknowingly have the "referrer" variable cloaked, in which case,
# if you have this variable set, they will not be able to submit
# your form.
#
# we suggest you make use of the next security measure: @recipients

$domain = "";

# ================================================================ #
# Var: $domain

#
# if a file is successfully uploaded, enter a URL to redirect to.
# use an absolute website address, as in :
#

http://www.google.com

# leave this blank to have the default message printed.

$redirect = "";

# ================================================================ #
# Var: @types
# ================================================================ #
# enter the file extensions for the file types you will accept.
# this script can upload any type of file. each file extension on
# a new line, or enter "ALL" in uppercase, to accept all file types

you should either check with your host or if you are using an FTP client such as
CuteFTP, change to the folder you are trying to upload to and look at the path you
have taken. You can see this just above the list of files on your server.
