My fault. After adding the necessary CRLF it works.
String sHeader = "HTTP/1.1 200 OK\r\n"
                           +" Server: Apache\r\n"
                           +" Content-Type: text/html\r\n"
                           +" Content-Encoding: gzip\r\n";

But when I receive the response I have only one header containing all header 
fields together [Server: Apache Content-Type: text/html Content-Encoding: gzip] 
and I can't iterate nor pick a special header out. I guess in my example above 
I should have at least three headers. Something else what I did wrong?

Kind regards,

Michael

Betreff: How to test compressed response

Hi all,

I just want to test the handling of compressed responses. I have some java code 
which can do the compression of content and which listens to http get requests. 
But I actually have no idea how to send the response respectively which 
streams/writers to use and how to combine the message header and the compressed 
content.
My last try was building a byteArray:

int contentLength = 0;
v

// parameter String message comes with call of method byte[] content = 
message.getBytes("ISO-8859-1"); byte[] compressedContent = new byte[1000]; 
byte[] bHeader; byte[] response; int numOfBytes;

Deflater def = new Deflater(Deflater.BEST_COMPRESSION);
def.setInput(content);
def.finish();
contentLength = def.deflate(compressedContent); sHeader += " Content-Length: 
"+contentLength; bHeader = sHeader.getBytes("ISO-8859-1"); numOfBytes = 
bHeader.length + compressedContent.length; response = new byte[numOfBytes]; 
System.arraycopy(bHeader, 0, response, 0, bHeader.length); 
System.arraycopy(compressedContent, 0, response, 
                 bHeader.length, compressedContent.length);

But on client side I receive a ClientProtocolException: Invalid header.

Any hints?

Kind regards,

Michael
