I am adding code to use a proxy server to access the Internet. The code works fine when requesting a file from a normal (HTTP) location, but does not work when accessing a secure location (HTTPS).
This is the code that works just fine:
URL = "http://UnSecureSite.net/file.xml"
Dim wr As HttpWebRequest = CType(WebRequest.Create(URL), HttpWebRequest)
Dim proxy As System.Net.IWebProxy
proxy = WebRequest.GetSystemWebProxy
wr.Proxy.Credentials = System.Net.CredentialCache.DefaultCredentials
Dim ws As HttpWebResponse = CType(wr.GetResponse(), HttpWebResponse)
// (more work here)
As soon as I change the URL to go to HTTPS, I get a 407 returned to me.
Almost like the proxy settings have been cleared.
URL = "https://SecureSite.net/file.xml"
Dim wr As HttpWebRequest = CType(WebRequest.Create(URL), HttpWebRequest)
Dim proxy As System.Net.IWebProxy
proxy = WebRequest.GetSystemWebProxy
wr.Proxy.Credentials = System.Net.CredentialCache.DefaultCredentials
Dim myCache As New CredentialCache()
myCache.Add(New Uri("https://SecureSite.net"), "Basic", New NetworkCredential(UserName, Password))
wr.Credentials = myCache
Dim ws As HttpWebResponse = CType(wr.GetResponse(), HttpWebResponse)
// (more work here)
Does anyone have a solution? Any help would be appreciated.
