Uploading big Files using CGI.pm

RT Users
1

Greetings,

This may be more of a mod_perl or Mason question, but I’m not sure at this
point.

I am using cgi.pm to upload attachments when creating a ticket in RT.
Everything is fine unlesss I try to upload a file large than 1 MB. This
generates an immediate server error and
on checking the Apache logs says ‘Malformed Multipart Post’.

I’ve read messages about Mason and CGI.pm problems, and tried in Webmux.pl
to fix it by adding this line after the ‘use CGI’ line:

$CGI::POST_MAX=1024 * 100000;

I thought that this would likely do the trick, but no go.

Is it possible that RT is limiting the size, or adding some other config
variable somewhere that I’m missing?

I’d appreciate any hints that anyone might have on this.

Thanks and cheers,

Brian Houston

Maybe this is a silly question, but did you restart httpd? Changes like
that only take effect with a restart.

Thanks Darren,

I did restart Apache, but that is a good guess.

I did finally solve the problem after three days of pulling my hair out.
Maybe my solution will save someone else from doing the same.

Our companny has an Internet Explorer only policy for Intranet
applications, of which RT is one. I kept getting a ‘Malformed Multipart
Attachment’ error in the Apache logs whenever I tried to upload a
file larger than 1 megabyte. I tried a million different things, and
finally in desparation got out the old copy of Netscape and tried it. It
failed as well, but instead of giving me the standard ‘500 Internal Server
Error’ I got an error from our Squid Web Proxy server. It turns out we
have a 1 megabyte limit on transfers in Squid.

I have no idea why Internet Explorer was not returning the error from
Squid, that would have saved me a lot of grief if it had.

Cheers,

Brian Houston

I do :wink: Tools → Options, cancel the stupid thing called “Display friendly
HTTP Error messages”.

Of course, from time to time, it will display them too, regardless of your
choice, but hey, it is a M$ product…On Fri, 28 Feb 2003, Brian Houston/NCO/CEtv wrote:
