(Apache) Web server configured to compress (gzip) responses for (Android) clients
Description
Since HTTP's Content-Length header returns the compressed size, it is an error to use getContentLength() to size buffers for the uncompressed data. Instead, read bytes from the response until InputStream.read() returns -1. See: http://android-developers.blogspot.de/2011/09/androids-http-clients.html
If the Web Server decides to compress the response of the deleteTree request you will get a Content-Length of 20 for a compressed (gzipped) empty body. This makes no sense but is valid.
