Options requests

Vote:
 

Hi

I have an application which works stable on Episerver 10 (still not updated to lastest version). However, we noticed that we have a lot of exceptions related to loading assets. The problem is that "something" is doing a lot of (Ajax?) requests of type OPTIONS. I believe it's not our part of code, because these kind of requests doesn't exists when you try to track all traffic in the browser or tool like Fiddler. What is more most of them are pointing not to the media files, but directories - so maybe it's a part of CMS?

Here is an exception logged in application insights, anybody has the same mess in logs generated by EpiServer? Any idea how to solve it?

URL: OPTIONS /globalassets/1.-intranet/3.-my-workplace/employment/recruit--introduce/attract/studentrelationer/

Could it be that the request comes from either a proxy or CDN in front of your site?

Thank you for your answer. Indeed, we have proxy server inside our company, so all users are going through proxy server. Do you think it can be the reason? I will try to contact our internal proxy admin to verify if it's true.
