So, you have a managed dump and you want to find out the request headers. Here’s one of the methods I use to find this information. I use it especially when I want to view the session ID or cookies.
0x120bea74 54000 Sec yes XXX 200 GET /default.aspx 0x14244228 54000 Sec no 284 Sec XXX 200 GET /default.aspx 0x1426f4c0 54000 Sec no 101 Sec XXX 200 GET /default.aspx 0x163a3038 54000 Sec no 193 Sec XXX 200 GET /default.aspx 0x1e0c360c 54000 Sec no 376 Sec 39 200 GET /default.aspx
String: Connection: Keep-Alive Cookie: ASP.NET_SessionId=5kwvjlzd3ksgii45ephn00aq; HTTP_REFERER::6841= Host: Skyraider User-Agent: DebugDiag Service HTTP Pinger
Hopefully this is what you wanted.
