Uploading Large Files

[=?Utf-8?B?RGFu?=]

I'm using a pure ASP upload script to handle file uploading. We run IIS6 and
I'm aware of the AspMaxRequestEn tityAllowed variable in the metabase. I upped
this to allow the file size maximum and it was working for the past couple
months. Now all of a sudden in the past couple of days we are seeming to have
problems.

The upload works fine for anything up to around 2mb (or so it seems).

When uploading about 20mb worth (10x2mb files), I get the following error
(thrown from firefox). I tried changing Response.Expire s,
Server.ScriptTi meout, and the connection timeout setting for the website in
IIS.

Connection Interrupted
The connection to the server was reset while the page was loading.
The network link was interrupted while negotiating a connection. Please try
again.

When uploading about 2-10mb worth of files, I get an error thrown by ASP.
The error typically just means that AspMaxRequestEn tityAllowed needs to be
increased, but since I've already increased it as high as it can go, I'm
really confused.

Request object error 'ASP 0101 : 80004005'
Unexpected error
/scripts/update/ShadowUploader. asp, line 58
The function returned |.

Line 58: strBinData = Request.BinaryR ead(iBytesCount )

" it was working for the past couple months."
If the code was working before, and no code changes have been made, then the problem must be something other than the code.

My thoughts exactly. I didn't necessarily say it was something in the code I
needed to fix. I'm looking for suggestions on anything that could be wrong.

I've already read that article, and many others I searched for off of Google.
I only ask for help when I can't already find it somewhere else.

I'm not using a component - this is a pure ASP file upload.

since the error message is coming from the request object, you're going to have to some debugging by testing uploads of different
types and sizes to better isolate and establish a repeatable cause of the error source.

Your previous testing of 2-10mb file sizes is a wide range, if the error is not consistently happening above one size perhaps it is
the type. otherwsie youi're faced with chasing the problem outside of ASP which is dependent on iis, memory etc.

I'm pretty well sure it's anything above ~6mb, which is just an odd figure,
since I have no limits set.

you may also want to try another component. if another works then you have a solution.

personally, for uploads and especially when they get large, I fall back to ASP.net because uploading is one of the few things
classic ASP just can't offer well by itself. Another option is a third party, registered component, which is a good alternative as
most webhosts have these freely available.

I'm using a pure ASP upload script. I've tried 3 other ones, all get the
same error. I also just used a third party upload component and got the same
error. I may look into ASP.NET, but only as a last resort. There must be a
solution to this, since it was working before :\

Thanks for taking the time to troubleshoot with me though.

My guess is that iBytesCount is not a chunk size but the total size right.
IOW, you are not chunking the data in but trying to read the whole lot in a
single buffer. OR am I wrong?
