    Preview node denied X-Frame-Options

    Hi,

    I'm not able to preview any node in Umbraco because the X-Frame-Options is set to "deny". Now this is true for the frontend, but within the:

    <location path="umbraco">
</location>

    I'm setting the X-Frame-Options to "SAMEORIGIN". Any ideas why the X-Frame-Options setting in Umbraco isn't working?

    /David

    Have you removed the header first? My tag looks like the following:

      <location path="umbraco">
    <system.webServer>
      <urlCompression doStaticCompression="false" doDynamicCompression="false" dynamicCompressionBeforeCache="false" />
      <httpProtocol>
        <customHeaders>
          <remove name="X-Frame-Options" />
          <add name="X-Frame-Options" value="SAMEORIGIN" />
        </customHeaders>
      </httpProtocol>
    </system.webServer>
  </location>

    Hi Alex,

    Yes, I do remove the header first. My header looks exactly like yours. :/

    Hi David/Alex,

    Did you fix this issue, I too have the same problem, and I updated the config files too.

    thanks.

    I'm also having this problem, after following Umbraco advice over X-Frame-Options, from their online security course

    They said to allow SAMEORIGIN for Umbraco location, to enable some of the functionality, but it appears to have broken the preview

    ... my workaround is to put the whole site X-Frame-Options to SAMEORIGIN, not as secure as DENY, but will still protect against clickjacking from another domain :)
