Not able to fetch an OCSP Response
Hi,
when i try to HttpGet the following URL http://ocsp.a-trust.at/ocsp
(which i can access in FF and get OK 200 with size -1 (no idea why)
its working as expexted) i get an
org.apache.http.ProtocolException: The server failed to respond with a
valid HTTP response
Can someone tell me whats wrong?
String uri = "http://ocsp.a-trust.at/ocsp";
HttpGet httpGet = new HttpGet(uri);
HttpResponse response = httpClient.execute(httpGet); -- here it will
throw the exception
HttpClient 4.2.1 and HttpCore 4.2.1

You can build a custom message parser and make it accept any garbage as
a valid message.

Maybe thats the problem because the execute call will throw an
exception. Is there any way to say "ignore the exception, everything
is fine, please return only the inputstream" ?
