generateToken request from Python and dynamic IP addresses generate errors

I'm having some issues with using tokens I generate from a Python script by hitting a public ArcGIS Server's generateToken endpoint.

Our IT routes traffic in some convoluted ways (which is to say dynamically) such that using a token generated from a generateToken request using 'client':'requestip' in the parameters sometimes will end up with a token denied error. Basically, if the generateToken request first comes from ip address B, but then the REST request comes from IP address B but uses the token generated from ip address A, I'll get an error.

I'm curious if there is a way around this somehow without going through IT. I'm unclear how I would use 'client':'referer' in the generateToken request, since this is coming from a Python script being run on a server and not a webapp. Is this even possible?

Every arcgis.gis.GIS and arcgis.gis.server.Server has an underlying connection object that has an underlying Requests session. You just need to set the token based on a referrer and then update your Requests session header to reflect it:

>>> from arcgis.gis.server import Server
>>>
>>> kwargs = {
...     'url': ,
...     'username': ,
...     'password': 
... }
>>>
>>> svr = Server(**kwargs)
>>>
>>> svr._con
<arcgis.gis._impl._con._connection.Connection object at 0x00000164C182FD68>
>>>
>>> svr._con._session
<requests.sessions.Session object at 0x00000164C6988128>
>>>
>>> svr._con._session.headers
{'User-Agent': 'Geosaurus/1.8.0', 'Accept-Encoding': 'gzip, deflate', 'Accept': '*/*', 'Connection': 'keep-alive', 'Referer': 'http'}
>>>
>>> svr._con._session.headers['referrer'] = r'http://www.whateveryoulike.com/myscript'
>>>
>>> svr._con._session.headers
{'User-Agent': 'Geosaurus/1.8.0', 'Accept-Encoding': 'gzip, deflate', 'Accept': '*/*', 'Connection': 'keep-alive', 'Referer': 'http', 'referrer': 'http://www.whateveryoulike.com/myscript'}

Thank you - I'm not using the Python API in this case, but just using requests directly. And yes, it was easy to add a referer header to my request directly and everything seemed to work nicely!

headers = {'referer':'https://myurl/myscript'}

data = requests.post(url, data, headers=headers)
