ASP.NET Alternative to iFrame to hide URL (Server-side Include?)

Hello,

I am looking for a solution (ASP.NET + VB) where I can include an external URL within an asp.net page.  I am basically looking for something similar to an iFrame except I don't want the user to be able to open the frame in a new window and get the URL.  The URL needs to be private/hidden.

I've seen examples of this in PHP I believe.

I know you can use javascript to block right-clicks and such but you can still view the source and that's a bit of a clunky / poor implementation.  Any ideas would be greatly appreciated.  

Thanks!

There isn't any method to block viewing the source code of a page that is currently in the browser.  In PHP, you can 'include' or use 'file_get_contents' to get the source of another page/file and put it in the current page.  But that does not hide the source.

Sorry - I don't mean hide the source.  I meant hide the URL.  Grabbing the source is OKAY… I just don't want the URL of the external page to be known.

I'm sure that VB.NET has a method for doing that but a quick search doesn't show what it is.  The biggest problem may be how the remote page is designed.  If it runs a lot of CSS and javascript to display correctly, it may not work to just 'include' it.

Is the url on the same domain where you can use an include file?  Or if you have legal rights to scrape, you can use xmlhttppost or at least I know you can use that in vbs. I'm not sure about ASP.NET / VB.  After a little searching, I think it is httpwebrequest that is equivalent.  http://msdn.microsoft.com/en-us/library/system.net.httpwebrequest(v=vs.110).aspx

It would not be typical that you have permission to do this though.  As example, trying to grab content from a travel or real estate site will have restrictions.  If it is a site you control, an include file would be the way to go if it is on the same server.

No, the URL is on a different domain.  The page is dynamic and visitors interact with the page so scraping wouldn't work.   Basically, a partner is providing the tool for us to use in our paid-members-only area… so I don't people that aren't paid members to be able to access it.

Then I believe you're stuck with an iframe.  Anything else you do will cause the interactive links to try to access your site and Not your partners site.

Oh that's too bad.  What's the best approach for minimizing how easier it is to find the iframe URL?  Not sure if there is a way.  Maybe disable right click?  Haha not sure.

I'm pretty certain that you can't hide it from me.  If you disable 'right-click', then I'll use "View Source".  Or I can view the headers to see what sites you are connecting to.  It has to be 'readable' for the browser to use it to connect.

Ya, I guess at the end of the day if someone is trying to find out, they'll be able to… but for most, they may not even know since it's not targeting a technical audience.

same issue here..
well you can use reverse proxy
you can use nginx, or iis and add rewrite rules
then you set iframe src to your_server_url , --> which will redirect to --> external_iframe_url
then the html rendered back and shown to the user.

maybe eveb without additional vm - https://tomssl.com/2015/06/15/create-your-own-free-reverse-proxy-with-azure-web-apps/

on the way , through your_server_url , you can check if the user is aloud to use the iframe or he reached some kind of limit of usage. then just return null to the iframe src
