Consider one scenario:
You have two web applications. There is a page in one web application (let’s say
Source web application). In this page there is button. On click the button you
need to open a Modal Dialogue Box. In this Modal Dialogue box, you called a
page located in another web application. If you try this, you will get bellow
error:
"Refused to display 'http://contoso/pages/home.aspx' in a frame because it set 'X-Frame-Options' to 'SAMEORIGIN'."
To get rid of this
problem, add the below line in the master page of the source web application:
<!--SPM:<WebPartPages:AllowFraming runat="server" />-->
It should look like
below screen:
Next you need to
download the following wsp from CodePlex:
This is a Farm Level
Feature. Download and install it in the central Admin and enable the feature
for both the web application. Now you can open the page without any problem.
