Downloading Large ZIP Files

[Kevin Antel]

Running ie6 and trying to download a large zip file from my iis 6.0 site.
When I go to download it, it's timing out. I can do smaller zip files just
fine, it appears to be 60MB and larger or 50MB and larger.

I've tried all the MIME changes and looked at all the KB's but still have
the problem.

Is this a known problem with IE or IIS 6.0?

Are you on a broadband connection such as cable, dsl or satellite? Does the
download actually start, or does it just sit there until the time out
occurs?

100MB connection in the office.
You get to the point where it tells you how big the file is and all, it
errors out between you saying save and the time when it asks you where to
save it to.

Check with your IS guy, they may have a firewall content policy on large
files to keep the individual users from hogging bandwidth.

I am the IS guy. An no, we do not have such policies. It's simple, the
large file can be downloaded by Mozilla but not IE. It can work between iis
5.0 and IE, but not iis 6.0 and ie. Smaller zips work fine between iis 6.0
and ie.

Check to see where the file is first being downloaded to.
(E.g. use FileMon from SysInternals.)
Often it is the TIF. How big is your TIF? Is it empty before starting?
Is the file being downloaded marked non-cacheable?
(You may need a packet trace active to determine that.)
Perhaps a TIF replacement algorithm is catching the partially downloaded
file and flushing it prematurely? FileMon could prove or disprove that
idea too. Leave the packet trace on (perhaps wrapping) to let you
find out the nature of the hang.


Good luck

I'm using IE 6 w/sp2, and have downloaded 200+mb files from MSDN w/o problem,
so it can be done. Robert had a good point, is the temp cache size getting in
the way. I've seen the problem with downloading from newsgroups, but it's
usually only when the C:\ partition is running out of space. Has it always
had the problem or is this a new development?
