I was getting an issue using the UnityWebRequest.Post method, described on this thread. It turns out that UnityWebRequest.redirectLimit is not working as expected for -at least- the UnityWebRequest.Post() method. The docs read about redirectLimit: If you wish to disable redirects altogether, set this property to zero. However, doing a POST request using UnityWebRequest.Post(), will follow 302 redirects regardless of UnityWebRequest.redirectLimit = 0; Then there is a second problem, UnityWebRequest.Post() asumes redirections maintain the POST method, when it may not be the case. In my original issue the initial request was using POST, but the redirection was expecting a GET request. Im not sure this is compliant with the standard, but is the reality of the vast majority of 302 implementations out there. I raised a bug report for my original issue, [Case 750104], yet this is the most accurate description of the base problems.
