Losing data in HttpResponse

[Jun Ma <mj...@gmail.com>]

I'm implementing a proxy server and I am using the example code to send a
http request and receive a http response. but I found that I am losing data
in the HttpEntity from the response.getEntity(), here is the situation:

int len1 = EntityUtils.toByteArray(response.getEntity()).lenth();
int len2 = response.getEntity().getContentLength();

and I found that len1<len2 and when I send out the response.getEntity() to
the client, I am losing data since the data send out in the 2nd connection
to the client browser is of len1 length.

I am using exactly the same code as the example code of HttpComponent,
what's wrong with my situation?

Best Regards,

There are CGI scripts out there in the wild that can generate incorrect
Content-Length header value. You may want to use a packet sniffer /
traffic analyzer to see exactly what packets get sent across the wire.
