ArcGIS Web Adaptor for ArcGIS Server

The ArcGIS Web Adaptor is one of the four components of ArcGIS Enterprise. Running in your existing website, the Web Adaptor forwards requests to your ArcGIS Server machines, typically forwarding incoming traffic on port 443 to 6443 and 80 to 6080. In addition, the Web Adaptor keeps track of the ArcGIS Server machines on your site and forwards and distributes traffic to only currently participating machines. The Web Adaptor also allows you to do the following:

• Expose your ArcGIS Server through your standard website and port by leaving off the default port 6080 (or 6443, if using SSL)
• Block the ArcGIS Server Administrator Directory and ArcGIS Server Manager from external viewers outside of your network
• Use web-tier authentication, such as Integrated Windows Authentication, to secure your ArcGIS Server

The Web Adaptor can be installed in your ArcGIS Server application machine, but is often put in an existing web server or a web server dedicated to GIS services.
