Get data from another website.

[Manuel]

I need to go to another website, login with a username/password and
retrieve a page.

The problem is that the site keeps track of the user with a session
variable + cookies.

I've done this in VB using the MS WebBrowser, Navigating to the login
page, setting the values of the textboxes and hitting
theSubmitButton.Click()
Then I just have to retrieve the data from the WebBrowser.

How can I do this in ASP.NET? Or some other way...

I recommend using Fiddler to watch exactly what's sent to and from the
server as you log in to the web page:
http://www.fiddlertool.com/fiddler/

Then you can use the HttpRequest method to post to the page and read
the response. You can then post or get other pages in the site.

Session variables are stored on the server, so you can't and won't need
to track them. You will probably need to get and set headers and
cookies, which are accessible via the HttpRequest / Response Headers
and Cookies collections:

This is also good if you need to handle ASP.NET forms authenticated

That is an excellent reference!
I used it awhile back and it actually worked.
Good explanation as to what is going on.
