Set up a reverse proxy server with ArcGIS Notebook Server—ArcGIS Notebook Server

A reverse proxy server is a computer that is deployed within a perimeter network (also known as a demilitarized zone [DMZ] or screened subnet) that handles requests from the Internet and forwards them to the machines in your internal network. By forwarding requests, the reverse proxy server masks the identity of the machines behind your organization's firewall, protecting internal machines from direct attack by Internet users. Additional security functions can be implemented in the reverse proxy server to further protect your internal network from outside users.

You can configure your ArcGIS Notebook Server site to use your organization's reverse proxy server. This is optional. If your organization does not use a reverse proxy, or if you don't want to configure your ArcGIS Notebook Server site to use one, you can proceed to configure your site with a portal.

Add ArcGIS Notebook Server to your reverse proxy server

Your organization's reverse proxy server must be configured to communicate with ArcGIS Web Adaptor by adding the corresponding URLs to the proxy directives.

For example, if you're using Apache as a reverse proxy server, you need to add the ArcGIS Web Adaptor URL to the ProxyPass directives in the Apache web server configuration file httpd.conf as follows:

ProxyPass /notebook https://notebookserver.domain.com/notebook
ProxyPassReverse /notebook https://notebookserver.domain.com/notebook

Set the WebContextURL property

If you're using a reverse proxy server and the URL to your site does not end with the default string /arcgis (all lowercase), you should also set the ArcGIS Notebook Server WebContextURL property. This helps ArcGIS Notebook Server construct the correct URLs on the resources it sends to the end user.

Note:

Use the WebContextURL property to set the ArcGIS Notebook Server URL to match that of its ArcGIS Web Adaptor (such as /notebook).

Do the following to change the WebContextURL property:

Sign in to the ArcGIS Notebook Server Administrator Directory at https://notebookserver.domain.com:11443/arcgis/admin as a user with administrator privileges.
Click system > properties > update.
In the Properties text box, insert the following JSON, substituting your own ArcGIS Notebook Server URL as seen by users outside your organization's firewall:
```
{
   "WebContextURL": "https://notebookserver.domain.com/notebook"
}
```
Click Update.
Restart ArcGIS Notebook Server. On Windows, restart the ArcGIS Server Windows service.

Reverse proxy headers and ArcGIS Notebook Server

When integrating your reverse proxy with ArcGIS Web Adaptor, the following property must be set in the header sent by the reverse proxy server:XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX">...
