I'm submitting multiple HTTP Requests via a DefaultHttpClient. The problem is that the "Host" header is never set in the request. For example by executing the following GET request:
HttpUriRequest request = new HttpGet("http://www.myapp.com");
org.apache.http.client.HttpClient client = new DefaultHttpClient();
HttpResponse httpResponse = client.execute(request);
The generated request object doesn't set the mandatory "Host" header with the value:
Host: myapp.com
Any tips?
My fault. Actually the DefaultHttpClient
do adds the Host
header, as required by the HTTP specification.
My problem was due to an other custom header I was adding before whose value ended with
"\r\n
". This has invalidated all the subsequent headers added automatically by DefaultHttpClient
.
I was doing something like:
HttpUriRequest request = new HttpGet("http://www.myapp.com");
org.apache.http.client.HttpClient client = new DefaultHttpClient();
request.addHeader(new BasicHeader("X-Custom-Header", "Some Value\r\n");
HttpResponse httpResponse = client.execute(request);
that generated the following Header sequence in the HTTP request:
GET /index.html HTTP/1.1
X-Custom-Header: Some value
Host: www.example.com
The space between X-Custom-Header
and Host
invalidated the Host
header.
Fixed with:
HttpUriRequest request = new HttpGet("http://www.myapp.com");
org.apache.http.client.HttpClient client = new DefaultHttpClient();
request.addHeader(new BasicHeader("X-Custom-Header", "Some Value");
HttpResponse httpResponse = client.execute(request);
That generates:
GET /index.html HTTP/1.1
X-Custom-Header: Some value
Host: www.example.com
