Hi,
To configure the LocalServer to capture http traffic you can run the LocalServerUtility from:
"C:\Program Files (x86)\ArcGIS SDKs\DotNet10.2.6\WindowsDesktop\bin\arcgisruntime10.2.6\LocalServer64\bin\LocalServerUtility.exe"
or
"C:\Program Files (x86)\ArcGIS SDKs\DotNet10.2.6\WindowsDesktop\bin\arcgisruntime10.2.6\LocalServer32\bin\LocalServerUtility.exe"
Cheers
Mike
