Allowing mp4 downloads from Windows server

Error 404 when file is on server

[kiwibrit]

I have a mp4 file which I would like page visitors to be able to download.

To do this the following code;

<asp:HyperLink ID="HyperLink2" runat="server" NavigateUrl="~/videos/stopMotion.mp4">1.8MB Quick Time file</asp:HyperLink>

results in the follwing html

<a id="ctl00_ContentPlaceHolder1_HyperLink2" href="videos/stopMotion.mp4">1.8MB Quick Time file</a>

Clicking the link results in a 404 error.

I do not get the same problem for a .wmv file - so I suspect this is a Windows IIS configuration matter. What should I ask my web host to do?

Solved by amending web.config file

<configuration>
 <system.webServer>
 <staticContent>
  <mimeMap fileExtension=".mp4" mimeType="video/mp4" />
  </staticContent>
 </system.webServer>
</configuration>
