Record Server Response to Log File

Hi all.

I am successfully posting to a remote server. I can see the last remote server response under the Debug Log but I’d like to save each response to a log file with only the server response like:

<result>
0
<msg>success</msg>
<leadid>453hdgsh</leadid>
<price>0.00</price>
</result>

Would much appreciate it if anyone can assist. I don’t seem able to find any log file.
