title: Excel template in sharepoint - how to open as a new file from template?
body: <p>I need to place an excel template in sharepoint and give people a link to it. I would like to prevent users from changing the template. I do not want users to save any file in the library. There are couple of solutions:<br>
  - revoke people sharepoint right to change the file,<br>
  - keep the file checked-out to me.  </p>
  
  <p>I also think about other scenario. Currently file is in <code>.xlsm</code> format (macro enabled workbook) but I am thinking about <code>.xltm</code> (macro enabled workbook template) as a way of forcing client excels to treat the file as template only. It looks like excel stubbornly wants to save the file (downloaded from sharepoint) as a template in source location and not as the new file. Only when I open the template directly from my local drive do I get what I need.
  How do I force sharepoint/excel to use <code>.xltm</code> file stored in sharepoint as a template for a new file?</p>
  
  <p>Isn't it a matter of incorrect http content disposition header?</p>
