In some organization you may meet requirements to remove the SharePoint version from HTTP response header for security reasons.
This is a snapshot of Fiddler response header from SharePoint 2013
Our goal is remove the MicrosoftSharePointTeamServices: 126.96.36.19920
To do this,
Go to “C:\inetpub\wwwroot\wss\VirtualDirectories\<your app virtual directory>”
In the web.config file go to system.webserver >> httpProtocol >> customHeaders
Add the following line <remove name=“MicrosoftSharePointTeamServices“/>
Go again to fiddler to see the result
NOTE: this may effect other applications like InfoPath.
