So we just recently moved our services from an IIS hosted .net framework 4.7 to linux hosted dotcore. There really wasn’t much change in doing so. However, we have since noticed that our LastModified headers sometimes work and sometimes don’t. We’ve got nothing more to go on and looking for maybe some ideas or direction on where to look.
Is there default configurations that are different between the hosting setup that would affect it? Or maybe because we have ngix in front of it? any thoughts?
Update - one of the developers things something in the cachcontrol options? They are not returning the same values between IIS version and dotcore version. We are getting private vs no-cache being returned.
