c# - Download file through code that has a redirect?

Question

I have some urls in the database. The problem is there urls are urls that redirect to what I want.

I have something like this

http://www.mytestsite.com/test/test/?myphoto=true

now if I go to this site it would do a redirect to the photo so the url would end up being

http://www.mytestsite.com/test/myphoto.jpg

Is it possible to somehow scrape(download) through C# and then have it redirect and get the real url so I can download the image?

Answer 1

I think you are after the HttpWebRequest.AllowAutoRedirect Property. The property gets or sets a value that indicates whether the request should follow redirection responses.

Example taken from MSDN

HttpWebRequest myHttpWebRequest=(HttpWebRequest)WebRequest.Create("http://www.contoso.com");    
myHttpWebRequest.MaximumAutomaticRedirections=1;
myHttpWebRequest.AllowAutoRedirect=true;
HttpWebResponse myHttpWebResponse=(HttpWebResponse)myHttpWebRequest.GetResponse();
