Question

I want to be able to run a little script that I can populate with a list of URLs and it pulls in and checks when the page was last updated? Has anyone done this?

I can only find a manual way of doing this using JavaScript by pasting this into the browser URL field

javascript:alert(document.lastModified)

Any ideas greatly received 🙂

The following will step through an array of URLs and display the last modified date or, if it’s not present, the date of the server request.

string[] urls = { "http://boflynn.net", "http://slashdot.org" };
foreach ( string url in urls )
{
    System.Net.HttpWebRequest req =
        (System.Net.HttpWebRequest) System.Net.WebRequest.Create(url);
    System.Net.HttpWebResponse resp =
        (System.Net.HttpWebResponse) req.GetResponse();
    Console.WriteLine("{0} - {1}", url, resp.LastModified);
}
