<p>How much detail to include is an interesting balance to strike; exposing the OS version is probably a bad idea, as mentioned in the earlier warning about overly-detailed values. However, exposed Apache versions helped browsers work around a bug those versions had with {{HTTPHeader('Content-Encoding')}} combined with {{HTTPHeader('Range')}}.</p>
