I'm running IIS 7 and when I'm trying to download a file from a public folder the server returns Error 500. However, this only happens on the first request and if I try again the download proceed as expected. If I wait for a period of time the problem recur.
It seems to be something with the session handling?
Isn't error 500 application related? This seems weird since it's just a simple file request?
Edit: I should mention that I'm using https if it could somehow be related.
