Finding Actual Directory WebClient is loading page from?

[Earl Teigrob]

I am loading a page using WebClient using the code below. The thing is that
on a redirect, I do not end up knowing where the page was loaded from. I
need this information because I am parsing the downloaded HTML page and
replacing Relative references with Absolute references. I have read that
this can be accomplished using HttpWebRequest but have not idea how to
implement it to retrieve the final destination directory. If anyone has the
actual code snippet to do this, it would be a great help.

Thanks in Advance

Earl


private string HtmlPageContent(string PageUrl)

{

WebClient MyWebClient = new WebClient();

byte[] bPageHtml = MyWebClient.DownloadData(PageUrl);

System.Text.ASCIIEncoding enc = new System.Text.ASCIIEncoding();

return enc.GetString(bPageHtml);

}

Not a big deal -- you send your request using (Http)WebRequest and check the
WebResponse's ResponseUri property:

// Method to download a (textual) web resource, UTF-8 encoding assumed.

public ResponseDto GetPage(Uri uri) {
WebRequest request = WebRequest.Create(uri);
WebResponse response = request.GetResponse();
string responseSource = null;
Uri responseUri = null;

using (Stream responseStream = response.GetResponseStream()) {
MemoryStream memoryStream = new MemoryStream(0x10000);
byte[] buffer = new byte[0x1000];
int bytes;
while ((bytes = responseStream.Read(buffer, 0, buffer.Length)) > 0)
{
memoryStream.Write(buffer, 0, bytes);
}
responseSource = Encoding.UTF8.GetString(buffer);
responseUri = response.ResponseUri;
}
return new ResponseDto(responseSource, responseUri);
}

// Data transfer object

public struct ResponseDto {
private string source;
private Uri uri;

public ResponseDto(string source, Uri uri) {
this.source = source;
this.uri = uri;
}

public string Source {
get { return this.source; }
}

public Uri Uri {
get { return this.uri; }
}
}
