Hi I need to evaluate if a server supports gzip compression.
Therefore I want to set gzip as Accept-Encoding in my request and evaluate if the response of the server containts "Content-Encoding: gzip".
However I am not quite clear on how to do this with HTTPURLConnection. Especially when to query my Connection object about the response. I currently do:
HttpURLConnection con = (HttpURLConnection) feedurl.openConnection();
con.setRequestProperty("Accept-Encoding", "gzip");
System.out.println("Current Accept-Encoding: "+con.getRequestProperty("Accept-Encoding"));
//check the response for the content-size
float feedsize = con.getContentLength()/1024f;
//the server uses transfer-encoding=chunked and does not specify
//a content length
if(con.getContentLength()==-1)
{
//count the content size manually
CountingInputStream counter = new CountingInputStream(con.getInputStream());
while(counter.read()!=-1)
{}
feedsize=counter.getCount()/1024f;
}
con.disconnect();
