Subject: Handle empty CONTENT_LENGTH environment variable.
X-Git-Tag: v0.59~155^2
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=96896eb092c3b4e0760e56d5228ef0d604951a12;p=ceph.git

Handle empty CONTENT_LENGTH environment variable.

nginx seems to be providing a CONTENT_LENGTH environment variable with no data
when the request body is empty.
