Can I configure IISxpress to only compress data from certain web sites in my IIS configuration?
Yes, IISxpress defaults to compressing everything, so you have to exclude the URIs you don’t want. This is done via the IISxpress Status window, select ‘Exclusions’ and then ‘URIs’. Select the ‘/’ item in the control, right click and select ‘Branch’ from the menu. All the items in the tree should now show in red, this means they are excluded.
