I configured the IIS to get the HSTS header. When I tried to verify using the curl command. I got the header sometimes and sometimes I'm not getting it.
In the below image you can see I accessed the same site using the curl command. The first time I got the HSTS header and the second time I didn't get it. Any help would be appreciables
I think this may be a problem with your configuration, you can install the following steps to configure HSTS:
Open the Internet Information Services (IIS) Manager via Start → Administrative Tools → IIS Manager.
Click on HTTP Response Headers.
Click on Add... in the Actions panel.
Enter the following values in the Add Custom HTTP Response Headers:
Name: Strict-Transport-Security
Value: max-age=31536000
