Problem uploading a file

[fionnmk]

I have simple code to upload a file to file storage. The file actually uploads fine although the log spits out this error continually.

`52373 [pool-1-thread-1] INFO root - {ab818704-fa6b-45c5-89a3-a335b6292ea0}: {Starting request to 'https://xxxxx.file.core.windows.net/xxxxx-container/TestFile6?comp=range' at 'Thu, 16 Aug 2018 10:50:20 GMT'.}

Any idea what's going on?
