asp.net - How to disable caching of single page application HTML file served through IIS?

Question

I have a single page application (angular-js) which is served through IIS. How do I prevent caching of HTML files? The solution needs to be achieved by changing content within either index.html or the web.config, as access to IIS through a management console is not possible.

Some options I am currently investigating are:

• web.config caching profiles - http://www.iis.net/configreference/system.webserver/caching
• web.config client cache - http://www.iis.net/configreference/system.webserver/staticcontent/clientcache
• meta tags - Using <meta> tags to turn off caching in all browsers?

IIS is version 7.5 with .NET framework 4

Answer 1

Adding the following into web.config solution worked across Chrome, IE, Firefox, and Safari:

<?xml version="1.0" encoding="UTF-8"?>
<configuration>

  <location path="index.html">
    <system.webServer>
      <httpProtocol>
        <customHeaders>
          <add name="Cache-Control" value="no-cache" />
        </customHeaders>
      </httpProtocol>
    </system.webServer>
  </location>

</configuration>

This will ensure that the that Cache-Control header is set to no-cache when requesting index.html.
