Wrong CONTENT_LENGTH causing truncated body

[jaycle]

Due to a bug in azure, when Content-Type is application/json the body gets formatted for pretty-printing, inserting spacing and \r\n into the raw body. The Content-Length header is left unmodified, however, resulting in a mismatch between wsgi.input and CONTENT_LENGTH in the wsgi environment. Ultimately, this causes the application to fail to parse the body since an application should not assume more than CONTENT_LENGTH is readable from the byte stream.
