Please, I need help with this problem.
I have a layer with 5 lines as roads, and all of they with a geocode.
Also, i have a mxd as a map service in a ArcGis Server 9.3.
I need to put the map of the service in a webpage across Esri Javascript, but filtering the roads across a GET or POST variable and highlight this road.
Please....help me !! and sorry for my english.
