Hello Pavan,

> Connect failed: HTTP/1.1 502 Proxy Error ( SSL port specified is not 
allowed.  )

HttpClient is hitting the wrong port at the proxy. Please
verify the proxy configuration you supply to HttpClient.

cheers,

HTTP/1.1 502 Proxy Error






Hi All,

The ProxyTunnelDemo.java program in Apache sample throws me the below 
error. Can some one point out what am I missing to do the Tunnelling. Will 
there be a problem if my proxy allows NTLM authentication.

[INFO] HttpMethodDirector - -I/O exception caught when processing request:
