Subject RE: [users@httpd] FW: uploading files using apache 1.3.2 > 1MB
Date Wed, 22 Oct 2003 10:56:17 GMT
Thanks for your input, I tested the upload on a new install of
apache/perl on my local machine, as everywhere else goes through 1 or
more firewalls, and it worked fine.

We are using a Linux firewall from Trustix but I cannot (yet) find any
documentation on it... our firewall config guy also doesn't know where
to find it or about the request limit, the firewall is going to be
changed for a Netscreen firewall.

The main server will be on the dmz and does not go through a firewall so
I'm told, so will test using a noisy modem or one of my machines at home
at lunch.

Plain text - PLEEEEZ...

We have a website where users upload files to our SSL server using this
mechanism. Testing locally, we demonstrated uploads of up to 20 MB
before we got fed up (the original spec was for files of around a few
100Kb). All went well in production for about six months until one
customer started getting failures... when his filesize went above

We finally tracked the problem down to an SSL hardware accelerator that
we had in the production DMZ. This machine happened to have a software
limit on upload filesizes which was set by default to 1MB. As soon as it
saw a Content-length of greater than 1048576, it dropped the packet. We
switched the limit to 20MB and all was well again.

Do you have some gizmo (bridge, router, firewall, load balancer..)
between your server and the WWW? If so, read it's fine manual and see if
it doesn't have a built-in limit on incoming packets.

Subject: [users@httpd] FW: uploading files using apache 1.3.2 > 1MB


Hi, I'm trying to upload files > 1MB using form enctype mutipart/data,
and all goes fine until just under 1MB.

I can upload multiple files at once less than 800kb in total and all
stays well, yet when I try and upload 1 or more larger files, I.E gives
me the page "Action Canceled", this means that it doesnt even get to the
cgi script!!!! 

 I wrote the cgi script to upload files myself, and its a first for me
so thought I'd use someone else's to test it (psupload), as it claimed
to be capable of 500MB+, yet I get the same problem...

This leads me to believe it may be a server problem...

I have looked around forums and mailing lists, and see that this is a
problem for many users using PHP and Apache (and have therefore
discovered solutions for PHP, Cold Fusion and another), but I cannot
find any solutions for my particular problem, I have also looked at the
LimitRequestBody but it is not in my conf files anyway, and I've tried
adding it.
Any ideas would be greatly appreciated...!
