I apologise in advance if this is not the right place to ask this question.
My client is having a problem accessing map image in WMS service. Error is "Error Code 499, Token required". The strange thing is that in our other identical test environments we don't have this problem. "Security for GIS services" features are disabled on all environments the same way.
I'm testing the service with a browser using the following url:
This returns a PNG image in our other environments but token required error in our production environment.
In the same environment this url returns XML without the error:
We use ArcGIS 9.3.1.
This is somewhat a serious problem and we can't proceed to production until we resolve this.
