Hello, I am working on a pet project and need to overcome a major hurdle in an application. I have checked countless forums and articles and have only found bits and pieces of what I am looking for, so I hope a more direct approach will help me.
Here's the scenario:
1. The site is actually a game, which uses Javascript/JSON with DHTML on a page that has several IFRAMES - two of which are deeper inside the outside page AND of a separate domain.
2. There are NO security issues with what I am trying to do. All programming and access is limited to merely simplifying and automating normally access functions only. All authentication and private information is done prior to any access, and only the session information will ever be used, and only to facilitate game operations that the user knows will happen.
3. The idea is to use the webbrowser control to access the game and provide ordinary access, while the app hosting the browser gets the game session information and makes separate automated calls to the game servers. This has already been done via Firefox using Greasemonkey scripting, and it works well - except that Firefox has a horrible memory leak that eventually causes the whole operation to break down.
The problem I am running into is obvious. I am trying to access the iframe that is technically on a different domain, and the web browser DOM model won't let me in. I have seen enough articles to know there are several workarounds to XSS filter blocks but they are quite vague and vary depending on scenario.
So, I will outline exactly what I need in hopes that I can obtain an amicable solution...
1. I need to obtain the DOM of a nested IFRAME of a different domain. If need be I could live with just the source, but the DOM and the JS vars would be the most ideal. My strategy here is to use the session information and make HttpWebRequest calls parallel to the web browser in-game. That way I can automate some functions while still playing. It can be done - if I can get the session information and pass it the same way. It will all be done on the same client with the users permission and knowledge, so no security issues.
2. I would really like it if I could pass information BACK to that IFRAME. One of the major things this project is trying to do is make some visual changes to simplify the look and feel of the interface. It is all in HTML, so changes would simply be adding some in-line styling of JS code...
So anyways, what ideas and suggestions would work best? At this point I am open to all scenarios, but ideally something as simple as possible to get what I need. This is already a huge project :).
Thanks in advance!
