I have an app making an https post on one thread while performing a
file download on another thread. For some odd reason, I am getting a
ClientProtocolException saying that "The server failed to respond with
a valid HTTP response". The error goes away if everything is run on a
separate thread.
Oddly if I run the two server requests in serial, the error goes
away. It seems there's a bug that happens when two requests are made
at the same time.
Important note: The post occurs to a different server than the
download so the servers themselves should not be causing the problem.
The code is simple. Here's the file download code:
HttpGet httpGet = new HttpGet(url);
HttpClient client = new DefaultHttpClient();
HttpParams params = client.getParams();
HttpConnectionParams.setConnectionTimeout(params, 15000);
HttpResponse httpResponse = client.execute(httpGet);
HttpEntity responseEntity = httpResponse.getEntity();
byte[] data = EntityUtils.toByteArray(responseEntity);
The post code's the same except for these additional lines:
HttpPut httpPut = new HttpPut(url);
httpPut.addHeader("Content-Type", "text/xml");
httpPut.setEntity(new StringEntity(postData, "UTF-8"));
BasicHttpParams parameters = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(parameters, 15000);
HttpClient client = new DefaultHttpClient();
HttpResponse httpResponse = client.execute(httpPut);
HttpEntity responseEntity = httpResponse.getEntity();
metaData = EntityUtils.toString(responseEntity);
Thanks,
Anthony
