where to include json web token

I maybe missing an important piece of jwt concept but I'm having a hard time finding info on where the server is supposed to include the generated json web token in the response and where the client is supposed to include it in the subsequent requests. Are there any rules/guidelines/best practices on that? The JWT should be sent to the client in the response body. In the subsequent requests you've got to include an header field called Authorization with the token. Check this link for more details. [XXX]

Webdriver.get() will not navigate to another page until I add wait before the call

I have a Python 3.5 script that basically logs into a web site (and gets redirected after login) and then navigates to another page where it actually does its job. If I run webdriver.get() to this second page right after the login, it doesn't navigate to the target location and stays on the page it gets redirected to after I log in. But if I put a breakpoint or just time.sleep(5) - it opens up fine. I found this question with the C# code, where it is suggested to add async waits. Is there a Pythonic way to work around it?My code for reference:# underneath is webdriver.Chrom...
