Do Caching working on my setup ?

[gfelot]

I have followed this part of the doc literally : https://ocelot.readthedocs.io/en/latest/features/caching.html

Then if I spam a request my first tough was to get a log like this : ConnectionId:**OcRequestId** => RequestId:**OcRequestId**:00000001 RequestPath:/api/stats/collected

and get a response from this cached request for the number of time I set it up.

Instead I got something like : Ocelot.Errors.Middleware.ExceptionHandlerMiddleware[0] => ConnectionId:0HLHK4OD3CE5E => RequestId:0HLHK4OD3CE5E:**00000004** RequestPath:/api/stats/collected

with the numbers that add up everytime... and the RequestIdKey is random.

That also make me see that the limit rate that I setup doesn't work too... Does the GlobalConfiguration part of my conf is working ?

ocelot.json

    "BaseUrl": "http://0.0.0.0:5000",

    },

        }
      ],
      "DownstreamPathTemplate": "/v4/home/get",

    }

}

                .AddCacheManager(c => { c.WithDictionaryHandle(); })
                .AddAdministration("/administration", "XXXXXXXXX");

        }

        public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
        {
            //console logging  
            loggerFactory.AddConsole(Configuration.GetSection("Logging"));

            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }
            else
            {
                app.UseHsts();
            }

            app.UseOcelot().Wait();
            app.UseHttpsRedirection();
            app.UseMvc();
        }
    }
}

Did I miss something ?

@gfelot I think the global configuration rate limiting stuff only applies if you are using dynamic routing. I think you need to set it per reroute.

I am confused by your issue, what is actually not working? Can you paste a full log?

[gfelot]

Yes I put the caching configuration for each route and it's working now. But it cache the response only by the checking the url. On a POST if I modify the JSON body, Ocelot send me the last response.

That last part looks like a bug to me, converting this issue.
