Question

I want to be able to map a path to a different domain but keep the original address in the address bar. Is there a way to code this or is it in IIS. I preferably would like a coded method if possible.

I have a link whose href is like this “http://www.example.com/invproxy.aspx?id=1&batch=1”.
I want to have that map to “http://www.otherdomain.com/Files/TheFileRequest.aspx”.

I generate the path to map to using the querystring of the original request. It works with Server.Transfer or Response.Redirect but i want the address bar to still say the originally requested URL. Is this possible?

Thanks

EDIT: I have solved the issue (probably not the most economical way) but below is the code I am using in the Page_load event of invproxy.aspx

// Just test file, no code to select path yet.
string requestPath = "http://www.otherdomain.com/Files/TestFile.pdf";

// Setup the request for the PDF File
HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create(requestPath);

// Get the response from otherdomain.com
HttpWebResponse resp = (HttpWebResponse)req.GetResponse();

// Assign the invproxy response the PDF ContentType
Response.ContentType = "application/pdf";

// Get the body of the response in a stream object
Stream s = resp.GetResponseStream();

// Create a byte array to  be read into from the stream
byte[] buffer = new byte[resp.ContentLength];

int position = 0;
while (true)
{
   //Read bytes one by one, slow but causes errors trying to read the whole thing.
   //I need to use chunks here.
   int b = s.ReadByte();
   if (b == -1)
   {
       //This is the end of the stream
       break;
   }
   else
   {
       //Set the byte at the current position to the value just read
       buffer[position] = (byte)b;

       //Advance the position by one.
       position++;
   }
}
//breakpoint debugging
string sa = Encoding.Default.GetString(buffer);

//Write the file to the invproxy response.
Response.BinaryWrite(buffer);

EDIT: Just to the add the finished result, I get my PDF document displayed in a new tab in the browser (where compatible) with the address bar saying http://www.example.com/invproxy?myquerystring

Based on the response above, I’d suggest using an IFrame to load the page that you actually want inside of the page whose URL you want the end-user to see. Keep in mind, this may have knock-on effects depending on how complex the contained page is.
