Hi Billy,

I have performed some research on this. Here is some information I've got
so far:

As for the ASP.NET client script based AJAX call, it is limited by the web
page script model. For all the web pages in webbrowser, webbrowser will
restrict the script to access pages on remote server. For example, if your
page is from http://serverA , if your script try use some script
component to send webrequest to other server/application, it is not
allowed. And this also restrict the AJAX method call to remote
applications(webservice or wcf). I've even tried call WCF on the same
machine(different server application), it is now allowed.

So far, one way to make such remote WCF method call I can get is create a
local server-side page method in which you use server-side code to call the
remote WCF service. And your page's client-side script call this
server-side page_method via AJAX. How do you think?

As you said, this also restrict the AJAX method call to remote
applications(webservice or wcf).

But actually I could call the web service in other IIS site by using Ajax.

Do I misunderstand you?

OK, please close it as resolved, thank you!

Thanks or your reply.

Yes, this is a "cross-browser" script restriction which prevent script to
interact with remote site(domain).

Anyway, so far for your scenario, two possible solutions are available:

1. use AJAX call to invoke local server-side page method and let
server-side to call the WCF service

2. Move the WCF to the local site/application(at least need to have the
same main domain server name) with your web page application.

If there is anything else need help, please feel free to post here.
