RE: HTTPAPIR4 gsk_secure_soc_write rc=406 issue

Hi Brad,

I have library G4MS on our system - I am sure I used it once before with
your help to test something.

I have downloaded a temporary key and applied and REGCHECK reports all is
good.

I am just not proficient at geturi.

Looking in Postman formatted for HTTP we have this

PUT
/bwitmasbu/SampleFile.txt?st=2024-10-01T00:22:54Z&si=FileUploads&spr=https&sv=2022-11-02&sr=c&sig=FhFz%2FW1evPlFrqm%2BDrxp3BUQAmS4iw%3D
HTTP/1.1
Host: bwitmasbu.blob.core.windows.net
Content-Type: text/plain
x-ms-blob-type: ••••••
Content-Length: 22

"<file contents here>"

Our test file is in the IFS '/backup/gen001'

I would like to use 32k chunks

Any chance you could advise how I would use the geturi command with that ?

Thanks
Don

If you're referring to the size of data for sending each chunk, that can
be set manually.
