How to access a 3rd party website Programmatically using HttpWebRequest?

Question

How to access a 3rd party website Programmatically using HttpWebRequest? 1)From my website i want to write code to login to another website using Login Id and password 2)Then After logging in i need to goto another page by clicking on a ling or button. 3)Then in the resulting webpage i need to update my personal info like password in a textbox and save it using save button. Everything must be done programmatically invisibly ie without displaying the webpages. Please can anyone help me by providing a working sample code simulating my problem.

Will the Sessions and Cookies from 3rd part website will be a Problem?

Hey what your asking is easily done but it is a bit tricky. HttpRequests / HttpResponse are exactly what you need to use. The CookieContainer in the HttpRequest object will look after all Session data for you (once you have logged in).Remember when you make a request and your expecting a cookie back initialize the CookieContainer in the REQUEST first. Otherwise your cookie will never be captured by the response. What you need to do is POST the login data to the 3rd party web pages that you log into.You will get a response but this will just be a big chunk of HTML which you will need to parse to see if what you did was successful. Upon succesful logon its just Request / Reponse over and back and POST data accordingly. Essentially its just HttpRequests and HttpResponses and parsing the HTML the response gives you back. Hope this helps Sailor.
