WinJS.xhr can't call web services in local machine or internal network?

Question

Hello guys.

I've noticed that I can't get to any Web service if they're not published on the web. Can anyone please tell me if this is a bug? Why does this limitation exist? I understand that allowing access to localhost is not something you'd want, but why can't I get access to Web services published in my internal servers? Does this mean that I can't build a Windows 8 metro app which gets data from the intranet? this can't be right...

Answer 1

Partially solved: intranet services require the home/work networking capability.

Now, I still need to access the Web service hosted in my machine. I've tried using the checknetisolation.exe tool but it still doesn't work. btw, here's the command I've run:

checknetisolation loopbackexempt -a -n=win8tests_t2ggmrgk4m9fg

(I've went into the manifest and I've used the name from the Package Family Name option of the packaging tab)

running the checknetisolation loopbackexempt -s, I can see that the rule was added:

 

PS C:\Windows\system32> checknetisolation.exe loopbackexempt -s

PS C:\Windows\system32>

 

Unfortunately, I still can't get the data from my app.

I've only managed to get the data from my service by opening fiddler2: after doing that, my local service is invoked and everything works as expected.

any thoughts??

thanks.
