NoHttpResponseException with proxy

Hi to all,

I'm developping a simple application that wants to use a proxy.

The client make a reqest, the proxy take this request and give it to the server.

This is the error

I/O exception (org.apache.commons.httpclient.NoHttpResponseExcep tion) caught when processing request: The server api.facebook.com failed to respond

I got this error when I try to make the post request to the server, when I'm into the proxy, like this

httpClient.executeMethod(method);

Somebody can help me?
