Re: Server-side mid-air connection close on upload

Michael, this looks a bit like the packets in between have been TLS handshakes which have not been carried out because the engine was not kicked off. Maybe a starHandshake() would help? Or can you share the full traces? Did you try http as well? Bernd -- http://bernd.eckenfels.net

Re: Server-side mid-air connection close on upload

Hello, the blocking code could use a different reader thread, but maybe that would be too much overhead? (Having a single polling thread might have a lower footprint but could create concurrency stress) The question is if the sync code could use available() after sending some buffers (not

Re: apache httpclient

Hello, Certainly you can use the Apache HTTPClient to replace URLConnection, you don’t need to do anything special on ARM other than having Java Runtime installed. If you have a slow http download changes are high this is caused by slow CPU, missing random numbers, slow network or server. All

Re: [HttpClient 4.5.5 ]Proxy-Authorization header missing while requesting HTTPS url

The scenario is different, with http you have the proxy and taget request being the same, with connect proxies they are separate requests. In both cases however you would not set the header yourself but use the appropriate authentication method on the proxy scope of the credential provider

Hello, I suspect it is a problem with too short DH keys offered by Java 7 clients. You can try to turn TLS_DHE_* ciphers off. According to SSL Labs it does also support ECDHE which should then work fine. https://www.ssllabs.com/ssltest/analyze.html?d=www.trf5.jus.br=189.39.123.181 Gruss Bernd

Re: Trust all certificates

The exception you are showing means the server terminated the handshake for some reason. Hard to say why. It might require a client cert or does not like yout proposed ciphers or ssl protocols. This particular exception seems not related to untrusted certificates, your different approaches are
