Problem in HTTPClient over SSL thru Proxy
Hi,
Am trying to connect to the secure URL say for instance "
https://java.sun.com/".
But unable to get the respose from the server with exception as
"Failed to download file.
org.apache.commons.httpclient.NoHttpResponseException: " (please see full
logs below)
By trying same piece of code with non-secure URL as "http://java.sun.com/",
able to get the web page content as response.
Is there any specifics to be considered in the below code to handle the
HTTPS case for proxy server settings.

Hello Sanjeev,
I couldn't find any initialization for the HTTPS protocol in your code
sample, unless it is hidden behind this call:
> BasicConfigurator.configure();
Did you follow the instructions in the SSL guide?
http://jakarta.apache.org/commons/httpclient/sslguide.html
cheers,
Roland

Sanjeev,
(1) What is the proxy server you are sending requests through? Does it
support HTTP/1.1? Anyways, try using HTTP/1.0 and see if that makes any
difference
(2) Fix all deprecation warnings in your code just in case
