I am working on sharepoint server 2013 web application. and i added a Page viewer Web part which is showing an external system. the url for the external system is (http://HRWebApplication). now when i access my sharepoint web application using http with sharepoint server name as follow http://SPservername/ the page viewer worked well.

but if i access my sharepoint web application using HTTPS + I used an alternative access name such as https://OurSharePointIntranet.intra the page viewer will not show the external system instead a white page will be rendered. so can anyone adivce what can be causing this ?

A Page Viewer webpart is nothing more than an IFRAME. loading HTTP content in an HTTPS site is a security risk so it is not allowed. You can try adding a HTTPS proxy, or a using IIS URL Rewriting on the target HRWebApplication machine to "trick" the SharePoint site and load the HTTP content through that.

More info here.

  • thanks for in the info , now modifying the external system itslef or the deplyed site on IIS is not a way to do in our case.. so what i can do from a sharepoint side to handle this ? is there a way to allow loading http content under https from a sharepoint-side?

  • It's not SharePoint, it's the browser. Loading HTTP content in an HTTPS secured site breaks security. PS, you would not be modifying the external site, buut add a HTTPS redirect site next to it with IIS URL Rewriting. The site itself would stay intact. The process used is SSL Offloading using Application Request Routing, An in-depth article on this can be found here: rdingwall.com/2013/09/24/…

  • Add empty site, add the following web.config (after installing ARR) <configuration> <system.webServer> <rewrite> <rules> <rule name="Reverse Proxy" patternSyntax="ECMAScript" stopProcessing="true"> <match url="(.*)" /> <action type="Rewrite" url="localhost:80{R:1}" logRewrittenUrl="true" /> </rule> </rules> </rewrite> <handlers> <clear /> <add name="Rewrite" path="" verb="" modules="RewriteModule" resourceType="Unspecified" /> </handlers> </system.webServer> </configuration>
