hi all,

Our customer has a requirement to extend the functionality of their existing large government project. It is an ASP.NET 3.5 (recently upgraded from 2.0) project.

The existing solution is quite a behemoth that is almost unmaintainable so they have decided that they want to provide the new functionality by hosting it on another website that is shown within the existing website.

As to how this is best to be done I'm not quite sure right now and if there is any security issues preventing it or that need to be considered.

Essentially the user would log on to the existing web site as normal and when cliicking on a certain link the page would load as normal with some kind of frame or control that has within it the contents of the page from the other site. IE. They do not want to simply redirect to the other site they want to show it embedded within the current one such that the existing menus etc are still available.

I believe if information needed to be passed to the embedded page it would be done using query strings as I'm not sure if there is even another way to accomplish this.

Can anyone give me some pointers on where to start at looking to implement this or any potential pitfalls I should be aware of.

Thanks
