>             Project: Chemistry
>          Issue Type: Bug
>          Components: opencmis-client
>    Affects Versions: OpenCMIS 0.10.0
>         Environment: (Apache) Web server configured to compress (gzip) responses for (Android) clients
>            Reporter: Achim Derigs
>            Priority: Minor
>              Labels: patch
>             Fix For: OpenCMIS 1.0.0, OpenCMIS 0.11.0
>
>         Attachments: patch

> 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. ;-)
