Hi, I noticed a strange behavior when using a jupyter lab server running on a docker image.

when I put this below in google chrome:  
**[http://localhost:8888/api/kernelspecs?token=4dc1910c6ba58541990ec8ad5fabacd5990113fd065f838c](http://localhost:8888/api/kernelspecs?token=4dc1910c6ba58541990ec8ad5fabacd5990113fd065f838c)**  
i get:  
**{“message”: “Forbidden”, “reason”: null}**

**When i put the exact same url in microsoft explorer, i get the kernelspecs json below. Any ideas why? I am trying to do the same with an html webapp and getting the same behavior than chrome ( ie no answer). thank you**

I did add “disable\_check\_xsrf”: true in the json config file (/home/sysml/.jupyter/jupyter\_notebook\_config.json) but no effect on the behaviour in chrome or the local webapp.
