upload big file don't work

[xkrizr01]

Hello,
when i try to upload file bigger than 2mb from my jsp page, browser shows "The connection was reset" page in a second.

If I connect to server with
Windows XP,
java 1.5,
tomcat 5.5,
commons-fileupload 1.1,
it works fine!!!

But when I copy the application to linux server with
debian sarge,
java1.5,
tomcat5 (with tomcat4, it was the same),
the above page is shown without any exception.

I tried parameter disableUploadTimeout, maxPostSize etc. Nothing helps...

Please help!

I have answer,
problem isn't on server side, but on client side.
Our proxy server doesn't allow to upload files bigger than 2mb.
It works fine from another locations.
