Issues with uploads on IIS - Solution

Been chasing down issues with uploads on IIS and finally found a solution so figured I'd post it

Issue was file uploads would fail if over roughly 5-10MB, confirmed not to be an issue with filerun by using one of many examples of php upload scripts found online

Turns out in IIS at the server level theres 'FastCGI Settings', this holds some server level limits on PHP, which is why no errors are logged in PHP.... Changing Idle Timeout, Activity Timeout, and Request Timeout to higher numbers resolves all the upload issues

Hope this helps someone
