问题
I am trying to upload video files larger than 2GB on an ASP.NET MVC 3 project however the maximum file upload size for ASP.NET 4.0 seems to be at 2GB. Is there a way to exceed this limitation in ASP.NET/IIS? or what would another approach be to get around this?
I am also using uploadify as my file upload control. Any help and resources for achieving this appreciated.
Cheers

According to my experience there is no way to upload file over 2Gb in a single request. There is a 2Gb limitation in IIS, and there is no workaround.
In .Net 4.0 and earlier there were also a 2Gb (some people say 4Gb) limitation in ASP.NET, that was fixed in .Net 4.5. However this fix makes a little sense because IIS itself does not support file uploads over 2Gb.
The only way to upload files over 2Gb to IIS-hosted server is to break it into pieces and upload piece by piece. Here are clients that can upload breaking a file into segments:
- IT Hit Ajax File Browser
- Sample WebDAV Browser
Note that these clients require your server to support PUT with Range header.
Another solution is to create a HttpListener-based server. HttpListener has much less functionality comparing to IIS but it does not have any upload limitations.
