I am trying to debug IIS + ARR in Reverse Proxy scenario. I have bunch of URL Rewrite rules that change the hostname of incoming request to another hostname, the requests come in via HTTPS. I need to capture the headers of the outbound request made by the ARR Reverse Proxy to the rewritten host.
The flow is:
Client calls https://originalhostname.com/foo/bar.aspx ARR receives the requests and rewrites it to https://newhostname.com/foo/bar.aspx After it hears back from newhostname.com ARR returns the response back to the client.
So i need to capture the request initiated by the ARR box for newhostname.com
I setup fiddler to intercept the outbound request following this link
Outbound requests are visible in fiddler and are decryptable too but the hostname of the requests is not newhostname but instead are all to the originalhostname. I do notice that a HTTPS Decryption tunnel is setup for the newhostname, but then i see the following in the fiddler logs and then the subsequent requests are all targeting originalhostname.
03:21:48:2877 Session #25 detaching ServerPipe. Had: 'direct->https/newhostname:443' but needs: 'direct->https/originalhostname:443'
What could be wrong? How can i debug this further?
