Lighttpd

Using Internet Explorer 7:

Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 1.1.4322; .NET CLR 2.0.50727; InfoPath.1; .NET CLR 3.0.04506.648; .NET CLR 3.5.21022)

downloading of the file interrupts with the error "The connection with the server was reset".

But I'm able to download the file using IE6, Firefox, Opera or using "wget".

The file on LiteSpeed server located at:
http://huronind.com/pdf/PTS_PDF_CATALOG.pdf

The same file on Apache server:
http://x-cart-hosting.com/PTS_PDF_CATALOG.pdf

IE7 was able to download 62780 bytes.

I checked response headers. There is only difference in the headers order(but possibly IE7 have something regarding order of the headers):
