I'm uploading 200 files and each file is between 1 - 2.5 MB in size.  I've run the test a few times and it usually stops working around the 80th file.   I will then click "cancel upload" and it will resume for another 10 or so files and then error out again.  I wish I could post an error message but I'm not getting any.  No javascript error, no asp.net debug errors.  It just stops working.  I'm using FF 3.5.

 

I've run this same test in the sample #2 mvc-c# application and it fails in the sameway.  I'm running the website on my local host using visual studio's debugging.  My url looks like this: http://localhost:61208/Samples/Sample2

 

Thanks for your help.

 

When I run this test on IE8, I get a javascript alert box.  It says, "http error1 :12031:Unknown"  Unlike firefox IE8 fails for every file upload.  Nothing gets uploaded using IE8.
