measuring response times when using HttpWebRequest class

[Guest]

I would like to be able to measure the following when using the HttpWebRequest class;
- host name resolution time
- connect time
- HTTP download time

I realize these metrics are not inherently supported by the class. Can you think of any way to measure these things short of writing my own HTTP implementation on top of Sockets?

Sort of.

1. Host name resolution can be done manually using the Dns class.

2. Connect time and download time can be tracked separately if you're using
async I/O. The callback to BeginGetResponse() could measure the connection
establishment, while the repeated calls to BeginRead on the response stream
could measure the download time.
