    I’m not sure if you want all of the things that you mention to execute ‘server-side’, but assuming that this is the case:

    01 – Connect to an HTML file on the
    web.

    Check out the WebClient class, and the HttpWebRequest class for more advanced scenarios.

    02 – Parse its content (text content).
    03 – Find out specific content in a
    page (for example looking for specific
    keywords).

    You might want to look at the Html Agility Pack, or if Bobince doesn’t notice, regular expressions.

    04 – How to submit information
    programmatically in HTML page (feeling
    forms).

    Typically, this will require sending a HTTP POST request, which too can be accomplished with the HttpWebRequest class.
