nginx-0.1.9-RELEASE importrelease-0.1.9

    *) Bugfix: the proxied request was sent without arguments if the
       request contains "//", "/./", "/../" or "%XX".

    *) Bugfix: the large compressed responses may be transferred not
       completely.

    *) Bugfix: the files bigger than 2G was not transferred on Linux that
       does not support sendfile64().

    *) Bugfix: while the build configuration on Linux the
       --with-poll_module parameter was required; the bug had appeared in
       0.1.8.
