SharePoint 2010 - Browsing to site gives a blank page (on server).

Issue:

          Browsing to the site results in blank page

Solution:

         

1) Go to Central Admin > Application Management

2) Click on "Configure Alternate Access Mapping" as shown below

3) As shown below, make sure the internal url is same as the external url (in this case http://localhost/)

Conceptually,

* Internal URL represents the incoming request to the website.

* PublicURL for Zone represents the outgoing response URL..

In otherwords, Incoming request can be different (like http://... or https://...) but when the response is sent it will be represented by a single URL (like https://...).
