We are going to discuss about the forward and reverse proxy server to state the difference between these two terms. Today, most proxies are web proxies, promoting a way to content on the World Wide Web, giving anonymity and may be used to circumvent IP address blocking. Proxies were designed to add arrangement and encapsulation to scattered systems. Moreover, the proxy server assesses the request as a way to explain and manage its complexity. A client combines to the proxy server by requesting services like a file, connection, resources available, web page, or another server. The way you set this header varies depending on your reverse proxy server implementation.A proxy server serves as a mediator for requests from clients asking resources from other servers. When troubleshooting communication between clients and ArcGIS Server or ArcGIS Web Adaptor, it is recommended that you set the X-Forwarded-Host header property in the reverse proxy server, as this is a common cause of communication failures. Also, the client will have some knowledge about the internal machine. This is problematic, as clients will not be able to access this URL (commonly noted as a browser 404 error). If the X-Forwarded-Host header property is not set, ArcGIS Server and ArcGIS Web Adaptor may return the URL of the internal machine where the request was directed, for example, instead of. For example, a request to the ArcGIS Server Services Directory ( ) is returned to the client as the same URL. If this property is set in the header, ArcGIS Server and ArcGIS Web Adaptor return requests to the reverse proxy server that match the reverse proxy server's URL. When integrating your reverse proxy with ArcGIS Server or ArcGIS Web Adaptor, be aware that both of these components expect to see the following property set in the header sent by the reverse proxy server:
#PROXY VS REVERSE PROXY SERVER UPDATE#
Update its Location header to ensure that the fully qualified domain name (FQDN) and context of the response match the server's WebContextURL value. Your reverse proxy server must be able to detect redirects (HTTP codes 301 or 302).
#PROXY VS REVERSE PROXY SERVER WINDOWS#
On Windows, this can be accomplished by restarting the ArcGIS Server Windows service on each machine.īefore deploying your reverse proxy server for use with ArcGIS Server or ArcGIS Web Adaptor, it is recommended that you configure some of the reverse proxy's headers to ensure proper communication. Restart ArcGIS Server on each GIS server in the site.The Apache web server configuration file nf: Need to add the ArcGIS Server URL or the ArcGIS Web Adaptor URL to the ProxyPass directives in
Your organization's reverse proxy server can be configured to communicate either directly with ArcGIS Server or via the ArcGIS Web Adaptor by adding the corresponding URLs to the proxy directives.įor example, if you're using Apache as a reverse proxy server, you Adding ArcGIS Server to your reverse proxy server For more information, see Health Check in the ArcGIS REST API.

This is useful to quickly determine if there's a software or hardware failure in the site. If your reverse proxy server supports a health check function, you can use the ArcGIS Server health check endpoint to determine if the site is available to receive requests.
Additional security functions can be implemented in the reverse proxy server to further protect your internal network from outside users. By forwarding requests, the reverse proxy server masks the identity of the machines behind your organization's firewall, thus protecting internal machines from being attacked directly by internet users. or screened subnet) that handles requests from the internet and forwards them to the machines in your internal network.
