We are using IIS 8 for serving static contents and angular UI code for our website. Added some custom headers in web.config recently for security vulnerability fixes. After this change , each custom header that is added is coming 2 times in the response headers.
<httpProtocol>
<customHeaders>
<add name="X-Content-Type-Options" value="nosniff"/>
</customHeaders>
</httpProtocol>
This issue we are facing only for one request where we are loading home page (index.html> Can any one help me how to address this one?
I am not sure on what to try for fixing this because the headers are specified in only one place - that is in web.config file.
