      Thank you Smita. Did you try the Fiddler standalone version? www.telerik.com/download/fiddler
      Might be good to check with company for exception to install this - great developer tool. Not sure of other ways to do this, could write some custom code, but haven't done that.

      are you using fiddler or fiddler everywhere version? Maybe you can try setting the HttpClient.DefaultProxy explicitly. You can find more details in this post/video www.rahulpnath.com/blog/jwt_authentication_asp_net_web_api/

I understand from your video the relevance of retry. Can you please help to understand the relevance of retrying HTTP call against timeout which is set up to infinite time(Client.Timeout = Timeout.InfiniteTimeSpan ) .

    • @RahulNath

      Yes, you can. Depends on what error cosmosdb is throwing and if it makes sense to retry. If the error is not transient, then retrying will only give you back the same error. Hope that helps.
