I'm having an issue I can replicate with windows 10 for a local intranet file hosting app. The site is only exposed on our internal domain, and specifically while testing, running on IIS on my PC. Site is deployed in ASP.NET, using a simple file upload via a FileUpload control and HTTPPOST.
Issue : Windows 10 CLIENTS take 8+ minutes to upload the same file a windows 7 CLIENT can upload in 40 seconds. The test file is 70mb. Both client PCs are on the same domain. I was able to replicate this on 2 windows 10 clients(slow) and 2 windows 7 clients(fast) both using chrome. Destination is a shared network drive, file is received in both cases
The code is simple, just using a file save as serverside when the post completes, the issue seems to lie in the POST itself being slow. I've included some information from the headers below from chrome. What I noticed is with the windows 10 clients, I'm seeing a request to "Switch Protocols" and then in addition a 302 response, Here are the header details for each below
What are we doing wrong?
Here is the "Switch Protocols" header only seen on windows 10 clients
