Big Config files cause failure in IIS #1084

Closed malekmakan closed 4 years ago

The issue is due to size of config file, I have added couple of new rule in config and Ocelot started to complain as below:

2019-12-19 04:59:30.7319 - ERROR: Connection ID "17365880169046218111", Request ID "80001580-0001-f100-b63f-84710c7967bb": An unhandled exception was thrown by the application.

also this might be interesting:

will breaking down the config file to multiple json files help?

I am running it on a Windows Server 2019 VM and IIS 10

Thanks
