SharePoint: From "Why can't I open PDF file directly" to "script attack"?

Let's start with a simple question.

Two days ago online, a netizen asked me such a question: "Upload to a SharePoint 2010 document library in a PDF file, when directly click on this file link, why browser pop-up dialog box only save, but not open?" ”

As the screenshot above shows, in the Browser pop-up dialog box, you can only allow the user to save the option, without an open option. But it may be remembered that in the previous SharePoint 2007, this was not the case. When a user clicks on a PDF file that is stored in a SharePoint 2007 document library, the browser prompts the user to open it directly, and then the locally installed PDF reader opens the PDF file directly and starts reading.

First, the way to solve the problem. Open SharePoint 2010 Central Administration, Manage Web applications, select a Web application, click General Settings in the Ribbon area, and then, in the Settings dialog box that pops up, change the "browser file handler" setting from the default "strict" to "license".

Get! You will notice that after you modify this setting, the browser will display the "open" option so that the user can open the PDF file directly.
