Check the page (URL)

[Just D.]

Does anybody know how can we check if the URL exists inside currently
running web application written in C#? For example I'm having the page name
like: "SomePage.a spx" and I need to know if this URL exists and I can safely
redirect to it or I should make some replacement for this url if it doesn't.
Can we control the method Response.Redire ct(SomeURL) ?

You probably want to do something like this:

if (File.Exists(Se rver.MapPth(you r_url)))
{
...
}

And don't forget to use System.IO

You would need to use an HttpWebRequest and an HttpWebResponse object to do
this. Create the HttpWebRequest with the desired URL, using the
WebRequest.Crea te(url) method. Then use the GetResponse() method to get the
HttpWebResponse . The HttpWebResponse will have the status code returned from
the server. This will tell you if the URL exists or not. 404 indicates "Page
not Found." 200 indicates "Success." Etc.
