Ok a problem has arisen today with FineUploader, it was working ok yesterday, and nothing has changed for the file upload part of the code.
The site is running on Windows Server 2008 R2, with IIS7 and all the service packs, and is running in MVC .Net 4.5.
The web.config has the required settings:
httpRuntime targetFramework="4.5" maxRequestLength="2147483647" and
requestLimits maxAllowedContentLength="2147483647"
to allow large uploads, and it works on a local machine in Visual Studio no problem.
I can also run it on a local machines IIS and it works perfect also. The only problem is when its run from the actual live website. Unfortunately I cannot give out the live site.
When it fails in FF I get 'XHR returned response code 0'
The code for the uploader (excluding the on error/complete etc.. events) is:
manualuploader = $('#uploader').fineUploader({
request: {
endpoint: '/File/UploadFile',
} });
So I do not limit anything of type/size etc... in the code.
As I say it will work 100% of the time for files under about 350kb, anything over and it always freezes at around the 350-400kb mark (based on the percentage it stops at). After a few minutes it goes to the error call of fineuploader with the XHR 0 code.
It works every time ok in Chrome, works sometimes in IE but sometimes freezing at about 1.5MB and gives same error code, and freezes 100% of the time in FF with that error.
Oh and I don't think its a timeout as it takes about 1 or 2 seconds to get the the 400kb even on a slow connection, and then just hangs before crashing. Any ideas?

Then the POST part is this (excluding the garbage at the end which is presumably just the file data):
