Title Body

Does anyone know how to screen scrape web-sites that use digest http authentication? I use code like this: var request = (HttpWebRequest)WebRequest.Create(SiteUrl); request.Credentials=new NetworkCredential(Login, Password) I'm able to access the site's mainpage, but when I try to surf to any other pages (using another request with the same credentials) I get "HTTP/1.1 400 Bad Request" error. I used Fiddler to compare requests of my C# application with Mozilla Firefox requests. 2 URLs that I try to access are: https://mysiteurl/forum/index.php https://mysiteurl/forum/viewforum.php?f=4&sid=d104363e563968b4e4c07e04f4a15203 Here are 2 requests () of my C# app: Authorization: Digest username="xxx",realm="abc",nonce="NXa26+NjBAA=747dfd1776c9d585bd388377ef3160f1ff265429",uri="/forum/index.php",algorithm="MD5",cnonce="89179bf17dd27785aa1c88ad976817c9",nc=00000001,qop="auth",response="3088821620d9cbbf71e775fddbacfb6d" Authorization: Digest username="xxx",realm="abc",nonce="1h7T6+NjBAA=4fed4d804d0edcb54bf4c2f912246330d96afa76",uri="/forum/viewforum.php",algorithm="MD5",cnonce="bb990b0516a371549401c0289fbacc7c",nc=00000001,qop="auth",response="1ddb95a45fd7ea8dbefd37a2db705e3a" And that's what Firefox sending to the server: Authorization: Digest username="xxx", realm="abc", nonce="T9ICNeRjBAA=4fbb28d42db044e182116ac27176e81d067a313c", uri="/forum/", algorithm=MD5, response="33f29dcc5d70b61be18eaddfca9bd601", qop=auth, nc=00000001, cnonce="ab96bbe39d8d776d" Authorization: Digest username="xxx", realm="abc", nonce="T9ICNeRjBAA=4fbb28d42db044e182116ac27176e81d067a313c", uri="/forum/viewforum.php?f=4&sid=d104363e563968b4e4c07e04f4a15203", algorithm=MD5, response="a996dae9368a79d49f2f29ea
