Twitter oauth(3)

Are you a Twitter expert? Requirement: Someone skilled in twitter is required. You need solid skills to handle this work. System: .NET 3.5 web, C#, .net project NOT .net website or .net winforms NOTES: Basic twitter logon is not acceptable for this task. All user details will be entered at the twitter website. Task: Using .net on a web page, oauth should be used to logon to twitter, get approval, and redirect back to the sending page which can vary. This means the sending page will store a cookie with its url which is then read by the [login to view URL] from the twitter handler and redirected back. After redirection, the twitter user name will be displayed and an option to logout will be shown. This method of using twitter is widely used online, and there are hundreds of sites using it. One example site us [login to view URL], another is [login to view URL] This task is unrelated to that site and others but those sites including mytweeple show the basic end user experience in terms of twitter logon. I have attached code as developed so far with demo keys, and this code partly works but has errors in cookie handling. This task will include full development of o1 as the handler and the code in the sending page which will be implemented at [login to view URL] which will allow users to post comments via their twitter names about products.
