Https request via proxy- getting refresh headers

Mon Apr 12 07:06:07 EDT 2010

I think you are still sending an HTTP request rather than HTTPS.  In
Netty, the URL doesn't have much meaning.  That is, replacing 'http'
with 'https' doesn't give you an HTTPS client automatically.  You have
to configure the pipeline to initiate an SSL connection and specify 443
as the connect port instead of 80.

For more information on making an SSL connection, please refer to the
latest HTTP client example:

  * HttpClient.java: http://is.gd/bptsB
  * HttpClientPipelineFactory.java: http://is.gd/bptsU

I'll publish the updated example to the web site once 3.2.0.CR1 is released.

BTW, what you really want is only HTTP(S), you could use this nice
library based on Netty:
