[HttpClient] Https performance and reverse lookup

[Christian Myrvold]

Greetings,

I am currently developing av http/https proxy app and are using the 
HttpClient to help me. My problem is that the performance is 
significally slower through my proxy than when I go direct.

The webservers I am trying to reach is usually on private networks (i.e. 
192.168.1.x) and over a dialup/PPP connection. This means that I have no 
dns-records for the servers and the HttpClient seems to be suffering 
from this when I use https. Cause when I add records in my DNS server 
for the webservers, I get a good performance gain. I asume this is 
because of reverse DNS lookup. So my question is how do I turn of 
reverse lookup for my app? Is it in HttpClient or in the SSL library? 
I've used the SSLSocketFactory that I found on this site. Please look below.

Also I would like to know if there are any good tips to ensure good 
performance with the HttpClient in general?

Help is greatly appreciated!

Best Regards,
Christian Myrvold
