Logging Into a site that uses Live.com authenticat

I've been trying to automate a log in to a website I frequent, www.bungie.net. The site is associated with Microsoft and Xbox Live, and as such makes uses of the Windows Live ID API when people log in to their site.

I am relatively new to creating web spiders/robots, and I worry that I'm misunderstanding some of the most basic concepts. I've simulated logins to other sites such as Facebook and Gmail, but live.com has given me nothing but trouble.

Anyways, I've been using Wireshark and the Firefox addon Tamper Data to try and figure out what I need to post, and what cookies I need to include with my requests. As far as I know these are the steps one must follow to log in to this site.

1. Visit https: //login.live.com/login.srf?wa=wsignin1.0&rpsnv=11&ct=1268167141&rver=5.5.4177.0&wp=LBI&wreply=http:%2F%2Fwww.bungie.net%2FDefault.aspx&id=42917

2. Recieve the cookies MSPRequ and MSPOK.

3. Post the values from the form ID "PPSX", the values from the form ID "PPFT", your username, your password all to a changing URL similar to: https: //login.live.com/ppsecure/post.srf?wa=wsignin1.0&rpsnv=11&ct= (there are a few numbers that change at the end of that URL)

4. Live.com returns the user a page with more hidden forms to post. The client then posts the values from the form "ANON", the value from the form "ANONExp" and the values from the form "t" to the URL: http ://www.bung ie.net/Default.aspx?wa=wsignin1.0

5. After posting that data, the user is returned a variety of cookies the most important of which is "BNGAuth" which is the log in cookie for the site.

Where I am having trouble is on fifth step, but that doesn't neccesarily mean I've done all the other steps correctly. I post the data from "ANON", "ANONExp" and "t" but instead of being returned a BNGAuth cookie, I'm returned a cookie named "RSPMaybe" and redirected to the home page.

When I review the Wireshark log, I noticed something that instantly stood out to me as different between the log when I logged in with Firefox and when my program ran. It could be nothing ~~but I'll include the picture here for you to review~~. I'm being returned an HTTP packet from the site before I post the data in the fourth step. I'm not sure how this is happening, but it must be a side effect from something I'm doing wrong in the HTTPS steps.

I'm not sure if you're still working on this or not but the Windows Live Development site has a lot of info on it to help with using the Live ID API. I've not had much of a dig into it but their Getting Started page has a load of info plus a link to download sample applications detailing how to use the service in a variety of languages (including C#).

You can download the sample application from there.

It sounds pretty interesting what you're trying to do, so much so that I quite fancy having a play with this myself!

Change your timing and see if you get the same results.

It is so much easier to just use a UI automation framework like WatiN than to use httpwebrequest, unless that would break your requirements. With WatiN, you are thinking about what is shown on UI rather than what is on the HTML.
