I have been going around in circles all morning using ASP 3 upload extension.
Server is Windows 2008 R2. IIS 7.5. I am using DW 5.5.
I have used many of your extensions over a number of years and normally all hunky dory.
The extension works fine on files under 2mb but just stalls on larger files.
I have read copiously the notes regarding numerous server settings and adjusted accordingly but the odd thing is that the error messages on my server are not reporting the info. Just seems that the incpu3class.asp is hanging.
I'm running into this too. About 75% of the time, a file larger than a few hundred kB will stall for about 90 seconds and then resume.
In my web.config: requestLimits maxAllowedContentLength="3000000000", so there should be no issue with file upload size affecting this. The uploads all work 100% of the time, but you have to wait waaaaaay longer than you should for 1 or 2 MB files (it takes minutes - not seconds). When the upload occassionally doesn't stall, it takes just seconds, but most of the time it will stall shortly after it begins for about 90 to 120 seconds, and then resume and finish.
If I got to my web host about this to talk to them about it, can you give me any information that might help isolate what the problem is - if it's not the extension?
