[Solved] Upload e.XMLHttpRequest.status wrong in IE

[Brian Edomm]

IIS returns a 404 error when the uploaded file size is > the maxContentLength setup in web.config. I'm checking for a 404 in e.XMLHttpRequest.status when there is an error to display a message to users that their file is too large. Tracing the request in fiddler clearly shows a 404 was returned by the server, and IE Dev Tools Network Capture shows a 404 was returned, but the value of e.XMLHttpRequest.status in IE 9/8 is 500 instead of 404. 

e.XMLHttpRequest.responseText contains the error message returned from the server wich says it was a 404. e.XMLHttpRequest.status is correct (404) in chrome.
