I'm maintaining an application that goes sort of like this:

There is a Page A with a Frame that shows Page B. Now page B is part of a completely different product, so there's a frame in a that just calls B.

Now, they want that when B an option in B is clicked, the WHOLE page is redirected to another page in A. The problem is that the url of A is something like "www.client.MyCompany/Order/Details/123"

But B doesnt know nothing about A, or which order # it is or anything, but Page A who has the frame B does know it.

For know my solution is to just redirect to all the order so something like client.MyCompany/Orders

but since B doesn't know which client it is, I'll add it in the webconfig. (so each client has its own webconfig with a different value).

I dont find this solution optimal but I can't think of anything else! I already tried putting the needed url in page A in a hidden Div (since A does know all the info) and then trying to read the whole DOM of the page from B to find it.... unfortunately I can only get access to Frame B's DOM... (I tried with jquery).

I know frames are evil, but this is how it is written... any ideas?

Thanks!
