How to set subsite page as main site home page

In SharePoint it’s easy to set main site homepage from main site itself.

But today I want to set my main site homepage using my sub-site webpage.

Solution:

    1) After little bit googling I am getting one of the way, we need to change the web.config file of SharePoint.

    2) To open web.config go to C:\Inetpub\wwwroot\port_number.

   3) Open web.config file and add following lines of code under system.web tag.

<urlMappings enabled="true">

<add url="~/" mappedUrl="/subsite/SitePages/Page.aspx"/>

</urlMappings>
